@thingywott I use them but only on macOS, both because it's the only OS doing them right and because it's a laptop where it just makes sense
@thingywott side-by-side with an option to put one or two apps fullscreen into a Space. There's side-swipe gestures to switch between them. Also when you open Mission Control you can see your Spaces, rearrange them, move windows between Spaces, move windows into fullscreen/splitscreen mode and move Spaces between screens, and switching Spaces on one monitor doesn't switch them on another https://support.apple.com/en-us/HT204100
@noiob oh! that does seem pretty handy~
it's definitely true that moving windows between workspaces in some things can be a paaaaain
not sure if i'd use side by side workspaces much though
