Greetings, I come as an Ubuntu/Unity user and what has kept me around is the wonderful support for a 3x3 virtual desktop setup and hotkeys to move around the desktops in 2d space. Does anything like this exist in any of the modern DE’s? I would love to try it out with cinnamon, plasma, gnome etc but there are so many and I only seem to find screenshots depicting linear desktops.
Cinnamon also has it. As to window managers alone, fvwm has a grid layout with the viewport freely scrolling over the virt desktops. The upcoming wayland compositor Wayfire also has a grid layout.
