Just tried the Bluetooth app for the first time. I'm really excited for when all the kinks get ironed out on this. Might even prompt me to get a wifi enabled Note size tablet for a virtual gauge cluster. But for now I have some feature/change requests:
Make the lap timer display on the Bluetooth app optional. It's not very beneficial to those of us who autocross, because we only make one "lap" at a time and I'd rather have the display space freed up for something else.
