It gets worse. Mission control is a complete failure.
Try working on 2 documents in Illustrator, 3 in Photoshop and 1 in Indesign, and having a couple finder windows open, Xee, and some other stuff. Youre currently in one of your photoshop documents and you need to find a file, open it in illustrator and bring it into photoshop.
In Snow Leopard:
show all windows all at once in expose, go to finder (any finder window) open in illustrator, copy object, show all windows again all at once and go DIRECTLY into the desired photoshop document and paste.
In Lion:
show all windows in mission control, and then get stuck with all finder windows being grouped together. randomly choose one and then find window. then open file in illustrator, copy object and use mission control only to find all photoshop document windows AGAIN be grouped, which the only solution is to pick the front document and hope its the desired one, and if not, use mission control AGAIN to fan out all documents within the application, requiring another useless step, just like the initial step with finder.
Who the hell was in charge of mission control?
And why is there no option in system preferences for mission control to show all windows at once without grouping?!
