    SwayFX: Sway, but with eye candy

    Sway is an incredible window manager, and certainly one of the most well established wayland window managers. However, it is restricted to only include the functionality that existed in i3. This fork ditches the simple wlr_renderer, and replaces it with our fx_renderer, capable of rendering with fancy GLES2 effects.

    notion

    notion

    Tabbed, tiling window manager.

    Notion is a tiling, tabbed window manager for the X window system: * Tiling: you divide the screen into non-overlapping 'tiles'. Every window occupies one tile, and is maximized to it * Tabbing: a tile may contain multiple windows - they will be 'tabbed' * Static: most tiled window managers are 'dynamic', meaning they automatically resize and move around tiles as windows appear and disappear. Notion, by contrast, does not automatically change the tiling. You're in control. Features include: * Workspaces: each workspace has its own tiling * Multihead: the mod_xinerama plugin provides very nice dual-monitor support * RandR: mod_xrandr expands on mod_xinerama and picks up changes in the randr configuration without the need for restarting Notion * Extensibility: Notion can be extended with lua scripts.
