I dunno. I just want a focus group on a desktop, where switching is related to the project I’m doing. For example one desktop vscode, iterm, browser. And another desktop about productivity.

The problem with switching is that you quickly get too many windows / apps.

I tried to have a user per group, but that does T work fast enough.

The best setup for me is 2 or 3 machines, linked with synergykvm

It's still easy to understand because it is just one rule, with no exceptions. Comparatively the OSX model is filled with arbitrary rules that depend on many factors (is another window of this app open in a maximised mode?, does the last desktop you were on have no windows?).

Even if, with time, you have become comfortable with it, it is still a more convoluted way to manage tasks.
