If I start an app and then open another, how do I get back to the first one other than going back to the home screen and selecting it all over again? My ASUS tablet has, in addition to the Home, Return, and Menu buutons at the bottom of the screen, another button that looks like two overlapped folders. Using it pops up thumbnails of all recent screens and you can choose which to go to. Is this a Honeycomb vs Gingerbread thing? Is there an app to do something similar with my Exhibit II? It's a real time/tap saver.
