Which sucks if you like me want to keep virtual spaces (or desktops) separated. I only want to see windows (or apps) running on the current desktop in the dock, which kind of breaks that (apple app) model i suppose. This is doable in windows (and a few DEs in linux) but not in Mac OS unfortunately.
