wow, thanks God I found this thread! I too think that 30’’ monitors cross the line between “great” and “so great that bothers me”… Initially I was astonished with so much space, but after a while you start to get tired of adjusting manually the windows, not being able to maximize, etc.
of all the links and solutions mentioned here I decided temporarily to stick with iShadow’s Virtual Display Manager. Still undecided if I’m going to continue using and pay the (expensive) 50 bucks they ask, but so far the experience was good. Also liked GridMove, and it’s a cheaper alternative to iVDM (even though I miss the functionality to ‘maximize’ a window to a virtual space). WinSplit is a no-go to me; felt it interesting, but not very useful at all.
thanks all for the suggestions and links!
