I think Spaces, like expose, is a wonderful productivity enhancement. However, the downside that I have found with Spaces is that using Command+tab still filters through all open applications instead of only those in each individual Space. The reason I wish that Command+tab would only filter through the applications/windows in each individual space is because of the following: Lets say that you have two applications/windows open in a space but at least one of the applications/windows is maximized to the full size of the monitor. If that window is the active window you will be unable to see the second window behind it. So how do you make the non-active window active? 1) you use expose to view both applications/windows and select the non-active application/window 2) you minimize the active application/window 3) you Command+tab through all applications/windows until you reach the inactive application/window. Clearly, options 1 is not a good one because then you might as well just use Expose and ditch Spaces. Options two and three aren't good choices because they take too long. So what do you do? Anyone know of a way or a program that will work with Spaces and force Command+tab to only filter through the applications in each Space? If so, you could use ctrl+arrow keys to move between spaces and Command+tab to switch between a couple of applications/windows in each of the Spaces. Sounds like a good homework assignment to me!
