I often find myself with multiple windows open that are non-interactable, (like the terminal window that I launch an X window from, or launch an app from, etc. [there are 3 in the screen shot]).
Would be nice to have the option to hide them…
Maybe it could be an option after long-pressing, when you get the little ‘x’ marks, and there’s a pulldown option to “close all”, there could also be an option to select windows to hide.
Or, maybe there could be an additional desktop you could slide them to…
