Projects, windows & files

Projects

A project is a VS Code-style single-folder workspace: a root folder plus its own saved session (open files with carets and pins, the active tab, folds, the editor-group layout, and tool-window layout). Projects are on by default since 0.10.0; Settings → Workspace turns them off.

The Project tool window shows the folder tree with keyboard navigation, a filter that runs a bounded project-wide filename search, per-file-type icons, and right-click actions: new file, new folder, new from template, rename, reveal, open terminal, local history, and Git stage/revert. The project root has its own menu too (with rename omitted so you can’t move the whole project). From the keyboard, F2 renames and Delete deletes the selected file, and the Menu key or Shift+F10 opens the selected row’s context menu (also in the Bookmarks, Notes, TODO, Git Log, and Structure tool windows). Renaming or moving a file or folder keeps its bookmarks, personal notes, breakpoints, fold state, and other per-file settings. Bookmarks and notes are scoped per project. Closing a project returns you to the global, no-project session.

Delete moves files to the system trash on Linux and macOS, and the confirmation says which will happen. Windows deletes permanently, as does any file the trash cannot take; a permanent delete asks with Cancel as the default button.

Drag files and folders onto a folder to move them. Dragging a single file moves it at once; dragging a folder or several items asks first. Undo Move in the tree’s right-click menu puts the last drag-move back.

Files open in any editor tab carry an accent marker in the tree; the active file uses a stronger marker. A file or folder menu can also add a first-line bookmark or Personal Note directly, with compact indicators showing both annotations.

Project Map

Use the Tree / Map switch at the top of the Project tool window, or Project: Toggle Tree / Map View (project.toggleMapView), to replace the file tree with a spatial canvas. The map shows the project as Miller-style columns: selecting a folder reveals its children in the next column, so the path to the current file stays visible without mixing unrelated expanded branches together. The choice of Tree or Map is remembered per workspace.

• Click a file to open it in an editor tab. Click a folder to select it and show its column; clicking a folder that is already open selects it and brings its column into view. A folder’s chevron expands or collapses it, and a column’s × closes that branch.
• Choose left-to-right (the default), right-to-left, top-to-bottom, or bottom-to-top flow. Connector direction and arrow-key navigation change together, and the flow is remembered per workspace.
• Drag empty canvas space to pan and use the mouse wheel to zoom around the pointer; Shift or Alt with the wheel pans instead. Fit, Center selection, Reset, and the overview recenter the layout.
• Drag a column header to reposition it and use its lock to prevent accidental movement. Columns size themselves to the longest loaded name.
• Filter globally by open, modified, Git-changed, bookmarked, or Personal Notes state and by file type. Matches and the folders that contain them stay prominent while everything else fades. Every non-root column also has a fuzzy name filter and a Show hidden checkbox.
• Click a file’s eye for a movable, resizable, syntax-highlighted read-only preview card. The preview uses unsaved buffer text when available and follows later edits; Open promotes it to a normal editor tab.
• A Personal Notes badge opens an independent editable note card for a file or folder. Note cards can coexist with code previews.
• Right-click a node for the same New, Maven, rename, delete, reveal, terminal, Local History, and Git actions available in the tree.
• The ? button lists the mouse and keyboard controls in a popover.

The options (⋯) menu holds Keep current zoom, Focus new column, Hide all open Personal Notes, Print… and PDF…. Keep current zoom and Focus new column are on by default and remembered per workspace, so opening a folder preserves the current scale and brings its new column into view. Turn either off independently; turning zoom preservation off restores fit-to-content when the map expands.

Hidden (dot) files follow Settings → Workspace → Show hidden files in the project tree. A column’s Show hidden checkbox overrides the setting for that folder only.

Image previews support common bitmap formats. Text and image cards keep independent zoom levels. At most eight cards are open at once, previews and notes together; opening a ninth replaces the one used least recently. Preview and note cards keep a live connector to their source row while the map pans or zooms and while a card is moved or resized.

The Project tool window’s search field searches the map too. A search reveals all the ancestor columns needed to reach its matches and selects the first one, and clearing the query restores the folders you had open.

Large folders

A column shows up to 300 rows of a folder and ends in a +N more… row that loads the next 300. Its header reads shown/total whenever a filter or a limit hides rows. The map as a whole shows at most 1,200 items; when that limit is reached the status bar says so, and closing a column makes room. An empty or unreadable folder opens a column that says so.

Keyboard

The canvas is fully keyboard-navigable.

These keys reach the map in every keymap while it has focus, including the chords a keymap binds to something else, such as Ctrl-N or Ctrl-0.

File management

The map also works like a mini file manager: multi-select files and folders with Ctrl/Cmd- and Shift-click, then drag them onto a folder (or the root) to move them, with open tabs following to the new path; a name conflict is skipped rather than overwritten, and a folder can’t be moved into its own subtree. Delete acts on the whole selection at once. Dirty files receive one Save/Discard/Cancel decision before the batch begins, and Editora records recoverable Local History before removing anything it has opened or edited.

Printing the map

Print… and PDF… in the options menu, or Project Map: Print… (projectMap.print) and Project Map: Export to PDF… (projectMap.exportPdf), output the whole map, not only the part on screen, with the current flow, filters, open branches and column positions. The output is light whatever the theme. A map that is wider than tall goes on a landscape page. A map too large to fit one page with readable labels is split across several pages, and the status bar says when the map was scaled down or split. Labels are drawn as an image, so the PDF’s text is not searchable. See Print & PDF export for the preview and the Save dialog.

With no project open, the Project tool window becomes a Current Folder explorer rooted at the active file’s parent directory, and follows the focused tab as you switch files.

Starting a project from a template

New Project From Template (project.newFromTemplate) scaffolds a whole project rather than pointing Editora at a folder you made yourself: pick a multi-file template, enter a project name and a location, and fill in the template’s variables. The dialog shows the folder it will create; a folder that already exists and is not empty is refused. Editora creates the folder, registers it as a project, and opens it in its own window on the template’s main file. A Python Project template ships with it (package layout, a test, pyproject.toml, README and .gitignore), and your own multi-file templates appear in the same picker.

Settings a project can commit

A project can carry a .editora/settings.json file saying which language server to run for a language, and whether to run it. It overrides your global preferences for anyone who opens that project. This suits the case where one repository needs a JDK 17 server and another a JDK 25 one, because nobody has to remember to flip a global preference when switching between them.

Project: Edit Project Settings… (project.editSettings) creates the file with an example and opens it.

Only toolchain settings can be overridden this way. Appearance, keymap and fonts stay personal, because checking out a repository should not rearrange somebody else’s editor. Run configurations have their own shared file, described in Run & debug.

Multiple windows

When projects are enabled, each project opens in its own window, with its own tabs, tool windows, and session. The window’s project picker acts as a window switcher: choosing a project focuses or opens that window. The set of open windows is remembered and restored on the next launch. With projects disabled, Editora stays a single window.

Launching Editora again while it is running hands the launch to the running editor instead of starting a second process. Start with --new-instance when you want a separate one; see the command line.

Tabs

Tabs are draggable to reorder and can be pinned. The tab strip, the switcher, and the Open Files picker all show the same unsaved-file marker. Close the last tab and the editor is left empty (it doesn’t recreate an Untitled buffer).

A file you’re only glancing at, for example while arrowing through a picker or following a definition, lands in a single reusable preview tab, shown in italic, so browsing costs one tab rather than one per glance. Editing it, or opening it explicitly, makes it permanent. See preview tabs.

Editor groups: two files at once

The editor area splits into independent editor groups, each with its own tabs and its own selection, so a header can sit beside its implementation or a test beside what it tests.

All five are bindable in Settings → Keymaps like any other command.

• Splits nest, so a side-by-side pair can hold a stacked pair and you can build an L-shaped layout. Splitting the same direction twice widens the existing row instead of chaining, which gives you three even columns rather than one column and a shrinking remainder.
• Drag a tab onto another group to move it there, or onto a group’s edge to split that group and drop the file on that side; a translucent highlight shows where it will land.
• Closing the last file in a group collapses it, so you never end up looking at an empty pane.
• The layout is saved with the session and restored on the next launch. A file that has since disappeared does not leave a blank pane behind.

Two views of one file

Separately from editor groups, you can split the current file into two views of the same buffer, which is useful for reading one part while editing another. The two can be combined.

Both views share one undo history: an edit made in one pane can be undone from the other, exactly once, and undo moves the caret of the pane it was issued in.

These commands are disabled on tabs that aren’t text buffers: the Welcome and Doctor pages and the image, hex, PDF and diff viewers.

Tool window layout

Tool windows live on three stripes (left, right, and bottom), and you can rearrange them without leaving the keyboard or reaching for a preference.

Maximize and float also have a button each in the tool window’s header, and the header’s right-click menu carries all three. Each acts on the focused tool window, or on the only open one; with two open and focus elsewhere, the command says so rather than guessing.

• Maximize expands a tool window over its split and toggles back. It is session-only and never saved, so a maximized window can’t reopen next launch covering the editor.
• Re-dock by dragging its stripe button onto another stripe. Dropping it on an existing button inserts it before or after; dropping it on empty stripe space appends it to that side. A window that was open stays open on its new side.
• Two windows can share a side, for example Project over Structure. Use Open in Split from the stripe button’s right-click menu, or view.splitToolWindow, which lists only the windows that could join a side right now. Left and right split vertically; the bottom splits horizontally, so that two consoles side by side both stay readable. A third window evicts the companion, not the primary. Opening a tool window normally still replaces, so the stripe buttons, keybindings, and palette behave as before.
• Floating puts a tool window in its own window, owned by the editor. It floats above the editor, minimizes with it, and closes with it. Bounds are remembered, and reused only when they still overlap a screen, so a window saved on a since-detached monitor is re-centred rather than opened somewhere you can’t reach. Closing a floating window closes the tool window; reopening it from the stripe docks it again.

Each tool window remembers its own size, rather than sharing one number per side, and the whole layout is saved with the session.

The Welcome page

With no session to restore, Editora opens a Welcome page (a real tab) with New / Open / Open Folder / Clone actions (each labeled with its shortcut), your recent files, and version and license info. Reopen it with view.welcome.

Focus modes

• Zen mode hides the chrome for distraction-free writing, with a small floating “Z” to exit. Toggle it from the palette (view.toggleZen), C-c z, or start with the --zen flag.

• Expert mode is a lighter focus mode than Zen: it strips only the window chrome (toolbar, tab bar, breadcrumb, tool stripes, whitespace guides) but keeps the full editor view, line numbers, status bar, minimap, column ruler, and current-line highlight, so you stay oriented. Toggle it from the palette (view.toggleExpert), C-c C-e, Settings → Interface → Modes, the floating “E” button, or the --expert flag. Expert and Zen are mutually exclusive, and like Zen it’s per-window and never changes your saved settings.

• Simple UI mode strips the editor to the essentials: it hides the extra toolbar groups, the tool-window stripe, the breadcrumb, the gutter, and the minimap, and turns off the heavier features (LSP, debugging, Git, multiple cursors) for a calm surface. Toggle it from Settings, the toolbar, the palette (view.toggleSimpleMode), or the --simple flag (session-only). Toggling off restores everything.

  It keeps a menu bar, simplified to File, Edit, Find, View and Help. The menus removed are the ones for features the mode switches off (code intelligence, running and debugging, version control, tool windows), which would otherwise be entirely greyed out. The menu bar stays because it shows what the editor can do, and people new to the editor need that most. The Simple UI mode toggle stays in the reduced View menu, so anyone who entered the mode from there can leave it the same way.

Window chrome

Each row of chrome can be hidden on its own under Settings → Interface → Chrome: the menu bar, toolbar, status bar, tab bar, breadcrumb and tool-window stripe. (Hiding the tool stripe takes precedence over each tool window’s own visibility toggle.)

Merge the menu bar into the title bar goes one further: the window is drawn without a system title bar, and the menus, the window title and the system buttons share that single row, which gives the editor a full bar of vertical space back. Minimise, maximise, close, drag-to-move, double-click-to-maximise, edge resize and snapping all stay the platform’s own, so the window behaves as before and only the position of the menus changes.

It is experimental, off by default, and applies on restart, because a window’s style is fixed once it has been shown. Linux and Windows only. macOS is excluded because the menu belongs to the system menu bar at the top of the screen there, so drawing it inside the window would not make the window any taller. The checkbox is disabled rather than hidden, so its note still explains why. Also on the palette as view.toggleExtendedWindow.

The breadcrumb sits directly under the editor area and is as wide as the editor, rather than spanning the whole window above the status bar. It writes your home directory as a single ~ crumb, which still navigates there.

In the status bar, indent, line endings and encoding are one segment (Tab 4 · LF · UTF-8), since all three describe how the file is written to disk. They remain three separate click targets with three tooltips, because they run three different commands, and they appear only when a file is open. A file whose lines do not all end the same way reads Mixed with its dominant ending, for example Mixed (LF). Saving such a file unchanged leaves it as it is; saving an edit writes the dominant ending on every line and says so.

The toolbar

Settings → Toolbar adds, removes and reorders the icons; right-click the toolbar and choose Customize Toolbar… to drag them directly on the bar (drag one off to remove it). Restore Default Layout puts it back.

The bar is two containers on one row. The icon cluster is what you customize, and it is what collapses into the overflow chevron when the window gets narrow. The tail is pinned to the right end and never overflows, the way an IDE pins its run widget. It holds the run-configuration selector with its Run, Debug and Stop buttons, the project switcher, Open Folder, the build badges and Settings. As a result, the selector and its Run, Debug and Stop buttons are not draggable items in Settings → Toolbar. They are pinned so that a narrow window cannot hide the control that starts a run, whereas every icon in the cluster is also reachable from the menus and the palette.

Recent Files sits in the cluster, between Save As and Undo. It is a file action, one of the ways to get a file on screen, and beside the project switcher it read as a project control. As a catalog item, it can be dragged elsewhere or removed like any other. A toolbar you had already customized keeps the button. Because a saved layout is used verbatim, the button is inserted after Save As so that it does not disappear from both halves.

Cut, copy and paste are not in the default layout, because in a keyboard-driven editor they are rarely reached for with the mouse. They remain catalog items and can be dragged back onto the bar. A bar you have already arranged is otherwise untouched.

Local file history

Editora snapshots your local files over time, independent of any version control, so you have a safety net even outside Git. A snapshot is taken on save, on auto-save, and before a file is reloaded after an external change. The first save of a session also keeps the text the file held before it, so the version you started from is in the history too.

The File History tool window (M-g l) lists each revision with its date, the reason it was taken, and its size (the latest tagged Current). Double-click a revision for a diff against the current file, then restore the whole revision or use the apply-chevrons to copy individual fragments back in (undoable).

It mirrors more of IntelliJ’s Local History:

• Named snapshots with Put Label (history.putLabel), shown bold in the list even when the content is unchanged.
• A filter over the revision list, plus a project-wide Recent Changes picker (history.recentChanges).
• A folder view: right-click a folder in the Project tree to list every file under it that has history, with deleted files badged; restore a revision to recreate the file. Deleting a file in Editora snapshots it first, so an accidental delete is recoverable (for files Editora had opened or edited).
• History follows the file. Renaming or moving a file from the Project tree keeps its revisions, and a file created with Save As starts with a copy of the original’s history once its first save is recorded (the original keeps its own). The copied revisions count towards the project’s size limit.
• Deleting history for good: Local History: Delete History of Current File… (localHistory.purgeFile) and Local History: Delete History of Project… (localHistory.purgeProject) remove snapshots permanently, after a confirmation that states how many snapshots go.

Restore validates the stored revision and verifies that the file has not changed while it was loading. If either check fails, the current file and editor contents are left untouched.

Snapshots are deduped by content and stored gzip-compressed in your config folder, pruned by configurable limits: snapshots per file, age in days, and total size (Settings → Workspace → Local History, or history.setMaxPerFile, history.setMaxAgeDays and history.setMaxTotalMb). Lowering a limit asks first when it would delete existing history, stating how many snapshots from how many files would go. It’s on by default, local-only, and off in Simple UI mode.

External-change detection

When a file changes on disk under you, Editora notices on window focus and tab switch and prompts to reload or keep your version. When the buffer has unsaved edits, the prompt says so and Keep Mine is the default, so pressing Enter keeps your version. The Project tree also re-scans on focus so files added or removed outside the editor show up, keeping your expanded folders and selection.

A file deleted outside Editora keeps its tab and its text: the tab is marked unsaved, the status bar says the file no longer exists on disk, and auto-save does not write it back. Save it yourself to recreate the file.

Trusted folders

A repository can ship its own build wrapper, ./mvnw or ./gradlew, and those scripts live in the repository rather than on your machine. Triggering a Maven or Gradle build runs one with your privileges, so a repository you merely cloned and opened could execute its own code on the first build.

Editora asks first. The first time you build in a folder it hasn’t been told to trust, it shows what would run and waits. Trust is remembered per folder and inherited by subfolders, so a multi-module repository asks once, and the default is always untrusted, including when the trust file can’t be read.

Declining means no build runs at all. Editora does not fall back to the mvn or gradle on your PATH, because that would not be safer: a hostile pom.xml or build.gradle executes code through those too, since build plugins and Gradle scripts run in-process.

Only the wrapper case is gated. Every other build tool (npm, Cargo, Go) launches your own toolchain, and Run and Debug always invoke a PATH interpreter, so none of them prompt.

Review or revoke trust in Settings → Workspace → Trusted Folders, or from the palette with workspace.manageTrust and workspace.revokeTrust. Revoking a folder that is still covered by a trusted parent tells you so, rather than claiming a revoke that the parent would override.
