I tried the Material Shell gnome extension, and toggled it back off.
It ate some of my settings, like the number of static workspaces I had, but that was easy to put back.
I can’t use Super + number now though. By that I mean normally I could press Super + 1, and it would launch Atom, which I have as the first favourite app in my dash. I don’t have dash to dock or dash to panel.
I can’t find any shortcuts in the settings for it. Does someone know how to get that behaviour back ?
