i love Gnome and it’s always my choice when i’m in Linux land (40 was a great step forward, with a much more elegant virtual desktop workflow for one) but as far as i can see, there’s no universal interface for global menus (that is exposed on the UI anyway, there may well be something exposed on dbus…)

incidentally, KDE apps sometimes do expose global menus, and there is a shell extension for this on Gnome, but it didn’t work in 40 last i checked.

but yes, it is the perfect jumping point for the kind of workflow i desire :)
