Bismuth KWin Tiling
KWin script to make KWin a tiling window manager: arrange your windows automatically and switch between them using keyboard shortcuts. All of that with different layouts and without a complicated setup of classic tiling window managers (i3, dwm or XMonad).
Bismuth features full KDE Plasma integration with multiple screens, Activities and virtual desktops; built-in KWin features (minimize, full-screen and rules); floating Dialog windows; multiple Layouts such as Classic Tiling, Monocle, Three-Column and Floating. It also works on the Wayland Plasma session.
