First, thanks for this app which is according to me one of the best available for outdoor activites on WP store !

A great additionnal feature could be the visualization of key indicators on the track (slope, altitude, speed, rate of ascent) right on the map with a detailed colour legend, especially for mountain biking (Alps). It could help us to understand quickly and graphically if the track is difficult or not on specific aeras (thanks to slope and altitude).
Here are some example on Runtastic (IOS) or MyTrails (Android):
MyTrails (with colorized tracks) :
