Comment 22 for bug 733349

I forgot about this multi-windows option...

But playing with it brings me to the same conclusion:
-I have 3 terminals on my desktop
-i click the lens, it shows me an expose view of the 3 terminals.
-if click on the lens again to "close" this expose view, and nothing happens.

Maybe I have terrible habits, but that's the first thing I noticed why trying it.
