Possible to have different desktop folders for different workspaces? - eviltoast

I am a “messy desk” person and like to have a big open visual space for all the pseudo-temporary files belonging to whatever project I’m working on at a given time. It would be nice to have a workspace specifically dedicated for “work” and still be able to create a fresh one when needed, without having to “put all the work stuff away” first. I’ve found GNOME extensions that allow different wallpapers, which is great, but I would love to have an actual separate desktop, not just windows.

Bonus points if I could change the dock applications and GTK theme too.

Running Ubuntu 22.04, btw.
