This is Amiga and Workbench, there are no good reason to clutter the screen with tons of windows in the first place, at least I never have this problem - bringing root to top is just a hotkey away. It would make more sense if it was more like macOS and the Workbench menu was _always_ there, even when other programs’ windows were active, but it’s not.
I can’t speak for others, but I never hide volumes, I only hide devices. For example on MIST I have both a fat95 SD0: and cachecdfs CD0: both scsi.device unit 1, and both mounted at boot - I use GhostBuster and its WB prefs and set both DS0: and CD0: to hide if not valid filesystem. Of course this feature is not in OS 3.2 because then users cannot format partitions, says ThoR. However, if I could hide ALL volumes and instead use arexx to open them rather than double clicking volume icons - I would! To be more precise, I would make icons on the desktop that would replace the volume icons, and havr them do much more than just open the drawers. Reminds me, on my wishlist is “triggers” for double clicking on workbench background and window backgrounds, with and without qualifiers, so one can configure double click on background to launch an arexx script, shift + double click to run a command etc. Same for windows, but with path to window being passed on as an argument.
The way Workbench works on 3.1.4.1, a hidden volume can not be opened AT ALL as a wb window, neither can any subdrawer, and left out icons are of course also not there. From previous comment by Minuous, this MAY have changed in OS 3.2, but I know better than to trust that
