Hi Henry,

Actually it does a little more now. It is meant to switch between different applications using the Reader screen. If you are on Dingo, a long press of that button brings up the wall paper privacy screen. If you open the calendar app and handwrite an agenda or to-do list, you can toggle between an open document, and open journal, and an open calendar. So, it is really for switching between applications, not documents. We have had a good number of requests to be able to have more than one document open, so maybe we will get there in the future.
