i3-wm 4.20.1 Tiling window manager
i3 is a tiling X11 window manager that dynamically manages tiled, stacked, and tabbed window layouts.
i3 primarily targets advanced users. Windows are managed manually and organised inside containers, which can be split vertically or horizontally, and optionally resized.
i3 uses a plain-text configuration file, and can be extended and controlled from many programming languages.
