Yeah, I've done that occasionally, too, but it adds a load of friction for moving windows between screens, in particular also when un-/replugging the screen, so it's still painful enough that I don't bother with a second screen.

I guess, it also plays a role that I do use lots of workspaces, so it's 1) extra painful and 2) I don't have as big of a need for a second screen, since I can just switch out what first screen displays very quickly.
