Access to all files , not only the sdcard

On my RAZR M with Jelly Bean, the actual external SD Card is found (in Airdroid) under /system/mnt/external1. That said, the Airdroid folks really should make it a configurable option on the Android app to let you specify the path of the actual external SD card instead of assuming it is /sdcard (especially since more and more /sdcard isn't the external SD card on so many devices).

I use a Galaxy Note 2 (GT-N7100).......would like the following (& so would lots of other folks):

1. Direct access to external SD Card(specify the path of the actual external SD card in settings)
2. Root access

Just bought a 3 yr premium account to help convince u t develope the above!
