In the android uncut version, reset views when switching tabs
After scrolling down the profile list, having to scroll back all the way to the top in order to refresh the list is pretty tedious - it is less of a problem in grid mode, of course.
In previous versions, switching from one tab to another would reset the view: maybe you could bring back this behaviour, if only as an option. My guess is that it would offer the additional benefit of reducing memory usage...
Alternatively, a refresh button could do as well, but it would probably cram the interface somewhat. Anyway, I guess you have ergonomists who overview these kinds of things.
