I still can't belive that there isn't the option to use it as a hot corner or for a special mouse button. Mission Control doesn't do the same job in many ocasions, like when dragging items between applications (you just can't because all windows are grouped up). Someone knows a workaround to fix that? Maybe a 3d party app? copying the SnowLeopard Exposé? I'm very angry with that, it was a very useful feature, and i'm thinking about installing SnowLeopard on a brand new macbook air just because of that (which is very sad, imo). Any ideas?
