How about showing the fullscreen preview switch on one monitor and leave it there permanently? Meaning, when I click on one of the screens the desktop will change, but the preview will remain visible rather than "minimize".

,

you can exclude monitors from desktop switching via 'Settings > Switching Desktops > Monitors'.
If you would like to assign particular virtual desktops to specific monitors: that's not feasible.

Hello!

I've just got my hands on a second monitor (my video card has 2 outputs) and I was wondering if I can have a virtual Dexpot permanently associated with each monitor and so I could view both of them at the same time. I thought I'd be able to do this via Windows alone, but I can't..

Thanks!
