I have used Linux on and off for 15 years. I consider myself a casual user and stuck to the mainstream DEs (mostly KDE, XFCE and some Cinnamon). Gnome has been a hurdle for me before and after the big version 40 changes, I couldn’t get my head around how they handled the workspaces and workflow. At some point I I tried out an extension hat changed all of it.
It moves the workspaces to a vertical panel and the programs onto a horizontal panel. In a workspace you can view the programs full screen or tile them.
Several Programs inside a Workspace. It’s basically they same way Gnome works. However for some reason it just makes sense in my brain. No idea why. (I’m looking at WMs that work in a similar way atm. Maybe I’ll take the plunge away from DEs at some point)
Has such a small change ever saved a Desktop Environment for you and is essential if you ever install it?
I don’t think Gnome, KDE and XFCE support moving workspaces between monitors. They only support moving windows between workspaces and monitors.
Sway/i3 have a single set of workspaces while most DEs have a set for each monitor. On these DEs switching between workspaces applies to all monitors.
That’s true, most WMs have a simplistic workspace geometry, where they spread a workspace across all monitors (regardless of their placement). I suspect that, since the workspace abstraction comes above monitors it may not even be possible for them to have a workspace split between monitors.
