Customized track styles for parts of tracks
As a mountainbiker I often try new trails and routes previousely planned on my pc or via Locus. In reality some of these trails are fantastic, some are not. And some you would definitely avoid going again.....
Problem is that years later you have no idea any more which part of a recorded track is worth riding again.
My suggestion: let user tag parts of a recorded track individually with several Colors (e.g. red as "avoid", Green as "super-Flow", yellow "difficult but worth it).
