I hated Mission Control ever since I got Lion, and I hate it more and more every day. Here's why: I can't rearrange my desktops The small thumbnail previews The fact that these previews aren't "Exposé-d" You can't change your desktop picture on all your desktops with one click Mission Control pretends to let you create and remove desktops "on the fly" by putting an "add desktop" button, and close buttons on each desktop, but then you realize that your app bindings to specific desktops get lost too easily Full Screen apps create new desktops, and you can't decide on their location Windows are stacked by application. I'm looking for a specific window, not an app. Let me see the windows one by one! Can't drag windows from one desktop to the other, unless you're dragging from the current desktop When you enter Mission Control, it takes me a long time to figure out which desktop I'm on of all the ones at the top. The faint grey border isn't obvious enough, and the actual desktop you're on doesn't "zoom out" into the thumbnail representation, so there's no good indication of where you are and it breaks your workflow. In Snow Leopard's Spaces, there was absolutely no question about which space is the one you were currently on, and where the other ones are relative to it. Desktops rearranging automatically is a mess, as you don't necessarily want to get to certain apps by clicking their icon in the dock, especially in full screen mode (dock is super-hidden). Turning that off completely makes you lose the ability to control the order of the desktops. I really feel that Mission Control should be about "controlling" your workflow, instead of completely losing control in this giant mess. However, I have found a semi-solution. I found that many issues come from the use of Full Screen mode, as it creates new desktops in unexpected locations, and it's impossible to change their location (even less than non-full screen windows). Moreover, Full Screen mode doesn't allow "Show Desktop" to work, and it completely goes against the idea of multi tasking. So the easy thing to do, is simply don't use Full Screen apps! You didn't have them in SL, why would you suddenly need them? Sure, they're nice and it's cool to have that much space, but it's also nice to be able to multi task and to make the best use of this ridiculous mess that is Mission Control. Conclusion: Stop using Full Screen apps, your workflow will become so much smoother!
