Live Wallpapers & Animated Backgrounds

Go beyond static images. Play MP4 video files, interactive HTML/CSS/JS canvases, and music-synced backgrounds as live wallpapers. Set different wallpapers per monitor and per virtual desktop.

  • Video wallpapers (MP4, WebM) with speed control
  • Interactive HTML wallpapers with full Web API access
  • Per-monitor and per-workspace wallpaper collections
  • Blur, saturation, and color overlay controls

Automatic Tiling Window Manager

Stop resizing windows manually. Seelen UI tiles every window automatically using BSPWM, Tall, Wide, or Grid layouts — fully keyboard-driven, with float and monocle modes when you need them.

  • 4 layout engines: BSPWM, Tall, Wide, Grid
  • Navigate and move windows with Alt+I/K/J/L
  • Float, stack, or monocle any window on demand
  • Per-app rules: auto-float, auto-assign to workspaces

Dock, Toolbar & Start Menu

Replace the default Windows shell with something far more powerful. A smart dock with auto-hide and window previews, a fully scriptable live status bar, and a faster, more organized start menu.

  • SeelenWeg dock — top, bottom, left, or right position
  • Fancy Toolbar — live CPU, RAM, network, battery stats
  • Smart start menu with apps, files, and web search
  • Custom Alt+Tab switcher with live window thumbnails

Clock, Media & System Widgets

Bring useful information to your desktop. Media player controls, a live desktop clock, CPU and RAM monitoring, notification center, Wi-Fi, Bluetooth, and more — all as elegant, lightweight widgets.

  • Media controls with album art and per-app volume
  • Desktop clock, calendar popup, and timezone support
  • System monitor: CPU per-core, RAM, network, disk
  • Notification center with Do Not Disturb toggle
