Archived - Feedback and Comments / Elevation Change on Track Profile?

I must say, this program is very powerful and useful to all that enjoy the outdoors.  I am greatly impressed.  There is one small feature I think could be added which would be worthwhile.  The elevation change (given in say -  meter of rise/2 meters of run) represented on the track profile.  I know the absolute elevation is given and where the colors change rapidly there is a large elevation change, but it would be nice to see this directly.  I also am aware there will be a lot of noise in this information.  You might be able to do something similar with a selectable menu similar to the Climbing Analysis page where you can determine the level of elevation gradient to choose from (mm rise/mm run, m rise/m run, m rise/5 m run, km rise/km run, etc…).  This should be easy since you have the elevation profile of the track.  Say the gradient is chosen as m rise/5 m run, then take the elevation at the starting point and then at 5 m down the track and subtract them and divide the difference by 5.  From the start to 5m down the track that segment will have the calculated gradient.  Just continue to do this all the way down the track until the end.  Give low gradients a light color and the high gradients a red color.  I hope this feature could be added easily.  I think it could add a valuable visual aid to this already great program.
