MC vs Expose
I just bought my first Mac after using them at my previous job for a couple years. Since I had a period of time not using a Mac during which Apple switched from Expose to MC, I might have a unique perspective on MC. Which is to say, it's not what I expected, but, neither am I totally ingrained with the behavior of Expose. Having said that, I have found that MC is unable to provide me with a view of tabbed browser windows. Even Windows 7 is kind enough to give you a couple different ways to discover your tabs quickly and easily through the task bar. (One of which OSX also provides; right-click on icon.)
When I was using a Mac before I found that I came to rely on Expose more and more. With MC, I find myself wondering about its usefulness. I don't want to say Apple needs to chuck MC, it seems interesting, it's just not totally "there" yet.
I think the problem is that App-Expose does nothing. MC is not bad, though the "spread" gesture should do more. The real issue is that once you find your app through MC, you're still in the same boat if you try to use App-Expose. App-Expose does nothing for tabs. I was expecting old Expose behavior for App-Expose, and that makes sense even in the context of MC. The problem with old Expose was that EVERYTHING got exposed. I work with web development so maybe my case is unique. The issue I used to have with old Expose was that I'd have the same page open in 3 browsers and it was hard to tell which one I wanted to see through old Expose. So MC makes sense for sorting that out. Where everything falls apart is with app-Expose, so I've found the app I want through MC, select it and swipe down, annnnd not a damn thing happens.
My suggestion is to have App-Expose function just like old Expose.
