In their own words
Seelen UI
Seelen UI is a free customization layer for organizing windows and changing the Windows desktop interface. It is designed for Windows 10 and Windows 11 and does not modify system files or fully replace the desktop. Its automatic tiling manager offers BSPWM, Tall, Wide, and Grid layouts, plus float, stack, monocle, and per-app rules. The shell includes a dock, scriptable toolbar, start menu, custom Alt+Tab switcher, and window previews. Background options include MP4 and WebM video, interactive HTML/CSS/JS, music-synced visuals, and collections assigned to monitors or workspaces. Built-in widgets include media controls, clock and calendar, system monitoring, notifications, Wi-Fi, and Bluetooth. The media module supports pausing, resuming, and skipping tracks with most music players. Documentation covers themes, widgets, plugins, and development; community support is directed through Discord, repositories, and other channels. Modified, debloated, or custom Windows installations are not recommended because removed components or disabled services may cause errors.
