Editora 0.16.0: navigate your project on a canvas
Editora 0.16.0 is out. Its headline feature is the Project Map, a new canvas navigator for moving through a codebase spatially without giving up the traditional file tree. Download it from the releases page.
The file tree gets a second view
The Project tool window now has a Tree / Map switch. Tree is the familiar hierarchical explorer. Map lays the current path across a canvas as focused Miller-style columns: open a directory and its children appear at the next depth, while the ancestors that got you there stay in view.
Only one branch is expanded at a time. Expanding a sibling replaces the branch below the previous sibling, so unrelated subtrees do not pile up into a dense graph of crossing lines.
The layout can flow left to right, right to left, top to bottom, or bottom to top. The connectors, column placement, and arrow-key semantics rotate together, so the arrow keys still match the layout whichever shape fits beside the editor. Pan by dragging the canvas, zoom around the pointer with the wheel, or use Fit, Center selection, Reset, and the overview to get your bearings.
Preview before opening
Single-click a file and a movable, resizable, syntax-highlighted preview floats over the map. It uses the current unsaved buffer when that file is already open; otherwise it loads in the background. Double-click the node or choose Open to promote it to a normal editor tab.
Folders expand with one click. File and folder nodes use the same themed icons as the tree, mark files already open in an editor, and show path, type, size, modification time, and editor or Git status in their tooltips. Right-clicking a node opens the same file-management menu as the tree, including New, Maven, rename, delete, reveal, terminal, Local History, and Git actions where they apply.
Filter the view, keep the context
The Project tool window’s search box becomes the map’s global fuzzy filter. Status chips narrow the canvas to files that are open, modified, or changed in Git, and a type selector focuses source, markup, configuration, or other files. Every non-root column has a fuzzy name filter and a hidden-file toggle of its own.
Global filtering fades unrelated nodes instead of removing them, so the layout stays put. Columns size themselves to their loaded names, can be dragged independently, and can be locked against accidental movement.
Made for the keyboard too
Arrow keys move along the selected flow and among siblings. Ctrl-N /
Ctrl-P step through a column, Page Down / Page Up jump by ten,
Backspace selects the parent, and Home returns to the project root.
Alt-Left / Alt-Right walk selection history, / focuses the current
column’s filter, and Escape fits the visible map.
The map is an additional view over the same project, not a second file-management model. It shares the project root, search, filesystem watcher, Git and editor state, sorting, icons, and actions with the tree.
Faster work behind the canvas
0.16.0 also changes how Editora handles background editor work. Highlighting, previews, completion, TODO scans, LSP synchronization, Undo History, and lint now share one settled-edit timer sequence per buffer and one whole-document snapshot per revision. Text files perform disk I/O off the UI thread, while CSV styling and slow external preview renders coalesce stale work instead of processing it after the document has moved on.
Preferences now live in settings.json, with project toolchain overrides in
.editora/settings.json; existing TOML settings migrate automatically. Find in
Files also has one consistent toolbar toggle, and recent files now include their
project names.
