Seelen UI reorganizes the Windows desktop with automatic window tiling, customizable shell elements, and desktop widgets. Its settings bring themes, layouts, keyboard shortcuts, and per-app behavior into one place.
How does Seelen UI arrange open windows?
The tiling manager places application windows into layouts such as BSPWM, Tall, Wide, and Grid. Keyboard commands can move and resize windows; Alt+I/K/J/L navigates between them. A window can be set to float, while stack and monocle modes provide other ways to manage the layout.
Per-app rules let users assign applications to workspaces or specify whether a particular app should float. Gaps and padding are configurable, and the custom Alt+Tab switcher displays window previews.
What can be changed in the desktop shell?
Seelen UI can replace or restyle elements such as the taskbar, dock, Start menu, and notification flyouts. The dock can sit along any screen edge and hide automatically; the toolbar can show live system information. Themes use CSS and JSON to adjust the appearance of shell elements, and the accent color can be derived from the desktop wallpaper.
- Set a different wallpaper for each monitor or workspace.
- Use MP4 or WebM video backgrounds, or interactive HTML-based wallpapers.
- Add widgets for clocks, system monitoring, weather, and media controls.
How do the launcher and media controls work?
The keyboard-driven app launcher uses fuzzy search to find applications, files, shell commands, and custom scripts. Media controls sit in the toolbar or in a widget, so playback can be managed without opening the player window. Available actions include play, pause, skip, and scrubbing.
Where are layouts and shortcuts configured?
A searchable settings interface collects options for themes, window layouts, keybindings, widget placement, workspace rules, and per-app overrides. Settings include a live preview. Configuration is kept in plain files, which can be version-controlled or synced.
