The big thing for me is a hotkey which launches a window I can put in an application (partial is fine) or command and it starts or runs the command.... so I do <Ctrl>+<Space>dark and it launches darktable. You can also have plugins that do things. So for example, after I upload my .torrent files, I delete them locally. So I have a rm command which just runs rm ~/Downloads/*.torrent.
Yes, I could click on the menu, type in the command I'm looking for but this is a little quicker. Plugins also allow you to do complicated tasks quickly.
I dunno, I've gotten used to it.
Oh, I've been a Linux user for a long time, mostly on the server, not as a Desktop. Unfortunately Fusion 360 kindof runs under wine but not really so it's still the one thing I have to reboot for.
