this stuff was huge for a while, 20-25 years ago, digital libraries, information exploration, ... consider even things like minority report, or more prosaically, all the demos coming out of MIT medialab.

It never really caught on, completed got clobbered by free text search, now AI chat interfaces I guess.

Am glad to see it bubble up again, because have good memories working on this stuff.

I think (work)spaces like macOS Spaces because they make access easier; with a single continuous space you have to work, whereas a workspace is a hotkey away. They make for nice demos and movie scenes though.

After having used such things since the 80s (starting with DESQview) I find myself simply minimizing or leaving secondary applications in the background of a single workspace. When I do use other spaces it is for full screen view. I don't usually need to see multiple windows at the same time, but that would be a task for a tiling manager...
