Add weather(wind) indicator
The issue with Strava is that every record, KOM etc is usually associated with a tail wind. It would be awesome if it could link into general weather info for each major centre and factor in the weather. Failing that you could add a user updated field that you could indicate the wind speed and direction, I suggest if you could drag an arrow over the map of your ride for direction and length of arrow relates to speed of wind. Also would need a way of handling wind change etc.
