Appearance Settings
Customize Omnilib's theme, fonts, and visual options to match your preferences.
Adjust how Omnilib looks and feels. All appearance settings are stored per-user and apply across all your devices.
Access these settings at Settings > Appearance (Cmd+, on macOS, Ctrl+, on Windows, then select Appearance).
Themes
| Theme | Description |
|---|---|
| Light | Clean, bright interface for well-lit environments |
| Dark | Low-contrast dark background, easy on the eyes at night |
| Omni | Omnilib's custom branded theme with distinctive warm tones |
| System | Automatically follows your operating system's light/dark setting |
Select a theme from the Theme dropdown. The change applies immediately without restarting.
Glass UI
Toggle Glass UI to enable frosted-glass morphism effects on panels, modals, and sidebars. When off, surfaces use solid backgrounds. When on, backgrounds gain a blur and transparency effect that shows depth between layers.
Colored file icons
Toggle Colored icons to show file-type-specific colors in the file tree (blue for TypeScript, green for data files, and so on). When off, all icons use a neutral monochrome style.
Font family
Choose from eight sans-serif typefaces and one monospace option:
- Quicksand (default)
- Roboto
- Open Sans
- Lato
- Nunito
- Poppins
- Source Sans 3
- DM Sans
- JetBrains Mono
The selected font applies to the UI and Markdown editor. Code and terminal always use a monospace font regardless of this setting.
Font weight
Select Thin, Regular, or Bold to adjust the overall weight of text throughout the interface.
Font sizes
Configure each context independently:
| Context | What it affects |
|---|---|
| UI | Sidebar labels, menus, toolbar buttons, settings |
| Markdown | Rendered Markdown preview and live editor |
| Code | Code editor and syntax-highlighted blocks |
| Chat | AI chat messages and input field |
Drag the slider or type a value directly for each context.
Markdown content width
Set how wide the text column is in the Markdown editor. The value is in characters (approximately). Range: 60–120 characters. Narrower widths improve readability for long-form text; wider widths let you see more content per line.
Collapsed sidebar by default
Enable Collapsed sidebar by default to start every session with the sidebar hidden. Press Cmd+B (Windows: Ctrl+B) at any time to expand it.
