is there a way to edit the menus? "right click" > edit menus doesnt seem to work...

I dont think its been done yet, you might check in with ifans though. Most likely if its done or being worked on youll hear it there first

I would like to say a way to use usb thumbdrives though, you can ftp to your device from inside bt arm and see everything you could from your android filemanager, so thats one way to get certain...

on my Acer A500 Tab they DO NOT work. you cant see any of the root filesystem or wifi/bluetooth etc. the wifi works but you cant configure anything deeper than the bt system itself
