Since Ubuntu 18.04 switched from Unity I have to learn how to use GNOME and tailor it to suit me. I installed the "Workspace Grid" extension to arrange the workspaces in a grid, just like Unity used to have it.
Now I'm looking into how I can make individual workspaces in the grid show a snapshot of the screen. I want to see all the apps open in a workspace when the grid pops up as I switch from one to another with CTRL+SHIFT+ARROW. Does anyone know how to do this?
