PaperWM is an experimental Gnome Shell extension providing scrollable tiling of windows and per monitor workspaces. It’s inspired by paper notebooks and tiling window managers.
Most functionality is available using a mouse, eg. activating a window at the edge of the monitor by clicking on it. In Wayland, it is possible to navigate with 3-finger swipes on the trackpad. But the primary focus is making an environment that works well with a keyboard like i3wm or swaywm.
