Compare Route / Route improvements

[sdfgsd]

I am using the route feature a lot.

I took someone's route and followed it. It was 100+k off road. It would be useful if I could
a) Compare how i did along that route compared to others. Currently, I have to open their route, measure where they were at a certain time, then open my route and see what time I hit the same location. - Having a similar flyover feature would be useful or the compare like you do in segments. I want to know if i am smashing the route, or being a slow coach.
b) Compare my route to theirs. If you use a Garmin, off road you know that its easy to go in a slightly wrong direction and rejoin the route a little later.... I want to be able to overlay their map with mine, to see where we may have deviated so i can either adjust my route or not.
c) Some kind of route repository where i can just browse local routes, you have it on the app but not on the desktop. I use the desktop almost exclusively because routing on a phone is a pain...
d) More granularity on surface types...  prefer road (but i don't want main roads) prefer dirt (i don't want sand) there should be bike tracks only and more types in the prefer x options, maybe even specifying percentage of surface e.g prefer road with 60% track.
