otter-overview is a one-shot overlay. Bind it to a hotkey. Workspace cards, window thumbnails, search, and an app grid. Click a tile to jump there. Type to launch an app. Escape closes.
It sits on zwlr_layer_shell_v1 overlay, on the output under the cursor. It is not a compositor.
Niri has its own overview. That one uses otter-wallpaper overview_enabled for a blurred backdrop. otter-overview is a separate app.
Usage
What you can do
- Click a window tile to focus it. The overlay closes first so it cannot steal focus back.
- Click a workspace card to switch to it.
- Drag a tile onto another card to move that window. Drag onto another tile in the same card to swap them. Drop on empty space snaps back.
- Hover a tile and click the close chip to close that window.
- Click the search bar, or just type, for the application grid. Enter launches. Escape clears search, then closes.
- Wheel or trackpad scrolls the card strip, or pages the app grid. Page Up / Page Down and the
< n / m >chips change pages. Arrows and Tab move between tiles or app cells.
Configuration
Config:~/.config/otter-shell/otter-overview.conf (fallback: /etc/otter-shell/otter-overview.conf). Created on first run.
Omit color keys (
overlay_color, card_color, card_active_color, card_border_color, tile_color, search_color, text_color, muted_color, accent_color) to inherit from theme.conf. font_path, font_size, and border_radius are optional the same way.
Thumbnails
Startup captures every window before the first paint, active workspace first. If capture is missing, tiles use a stable per-app tint. Hyprland can also usehyprland_toplevel_export. Other compositors use ext-image-copy-capture when present.
