> On MacOS and Windows [...] the virtual desktops there are usually just a single stack behind the scenes, and they are not per screen I'm not using a mac anymore, but last time I checked, this wasn't true. You could have per-screen virtual desktops, meaning you could have screen 1's virtual desktop stay put while you switch desktops on screen 2. The setting was easily accessible, too. In Settings -> Mission Control IIRC.
