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?
Oh, true, you don’t get previews of the windows inside. However, that shouldn’t be very hard to implement, so you might have luck if you ask for it to be in Plasma 6.
