Here's a view of the ´Dual Browser´ app creating split windows for the Galaxy 10.1 Android tablet. Clicking the top right corner in each window will show the selected window in full screen
size. Each of the two windows can have many different URL bookmarks. With MY version 4.03,dual windows is only possible using browser URL´s,in other words NOT for resident apps.
(Sorry. uploads does not function at the moment)
