Average Power, HR etc
Customisable On Screen Data
Lap Button
Power Smoothing
Ability to have customisable workouts
Oh and a Power meter callibrate button!
Definitely want a LAP button, that is my number one request
It would be great to see average power and last lap average power. Plus a larger lap counter. The one under the side bar/name area is tiny and hard to see. A customizable set up screen in user profile or settings could let each person build their own display so they see exactly what they desire.
