I do not run ANYTHING full screen except my Windows 10 KVM on workspace 2. And that is only a single monitor.
I hate full screen.
I stack stuff around. So I always see some piece of the background some place.
Same here, always a ton of things open, never see my desktop. Any desktop widgets or icons or whatever would be completely useless to me. If I have to minimize everything to get to something on my desktop, it'll set me back and waste time bringing stuff back up. I position things so I can click a window behind something running in front of it (when I can or makes sense).
I run my web browser 80% of the time maximized on a separate monitor, VMs on another virtual desktop. The rest of it is stacked windows everywhere.
I use alt+tab a lot to find windows easy, too.
