Hmm that's a good idea, provide a view of generic system and the app itself..

Android added one time / during use / all the time, but has yet to add filesystem granularity, though I suspect even if they add that, the app will just ask for access to the root directory.

Interesting, I wonder why..

This was my first thought also, but then I realized they'd just see there's no system files (or some marker file their app created) and block access.
