Another frustration is that Mission Control does not play nicely with multiple displays. It would be nice if each desktop would display on a separate display. So desktop 1 would display on my first screen and desktop 2 would be on my second screen, then when I do a three finger swipe it would then switch to displaying desktops 2 and 3. This way makes so much more sense. That would also resolve the issue of full screen apps leaving the second display blank.
I've seen this issue brought up on the web all so often, you would think Apple would get on the ball to fix this.
I almost wish I could write an app that does this. Does anyone have any insight on how to do this? Does anyone know if one like this is already in development? This functionality is crucial to my workflow.
