Themes & fonts
Appearance settings live in Settings → Appearance, which includes a live preview that recolors as you change things.
Themes
The app chrome is themed by AtlantaFX. The editor surface, gutter, syntax tokens, and project tree are themed separately, with six editor color themes:
- Primer (the default, GitHub-style)
- Nord
- Cupertino
- Dracula
- Islands (JetBrains-style)
Each comes in light and dark. By default the editor theme follows the AtlantaFX app theme; pick one explicitly and it sticks. A theme colors the syntax tokens, editor surface, gutter, and the Project tree together.
The Markdown preview can be themed independently of the app with its own light/dark toggle (a sun/moon button on the preview’s zoom control), so you can read a GitHub-style light page inside a dark editor.
User themes: drop your own theme CSS in a themes/ (app + editor theme) or
editor-themes/ (editor only) folder in your config directory,
and it joins the picker. Theme: Reload User Themes (theme.reloadUserThemes)
picks up changes without a restart.
Fonts
Five monospace families ship with the app, so nothing needs a system install:
- JetBrains Mono (default)
- Cascadia Code
- Fira Code
- IBM Plex Mono
- Source Code Pro
They’re listed ahead of your system monospace families in the font picker. The Markdown preview and PDF prose use Inter on every platform.
Text zoom
Zoom the editor text independently of the configured font size:
| Action | Default key |
|---|---|
| Zoom in | C-= |
| Zoom out | C-- |
| Reset | C-0 |
Ctrl+wheel zooms too, and the status bar has − / + buttons. When the active
buffer is a Markdown preview, the same gestures zoom the preview instead of the
editor text. The zoom level is saved as fontZoom and isn’t shown in Settings.
