As in I want all the routes generated to have at least x meters of positive elevation or/and at most x meters of positive elevation
Thanks for suggesting this. This idea has come up before and we have given it some thought but I think it would be very difficult to implement.

Thanks for your answer, I understand It may be difficult to implement, this features interests me a lot as I do some trail running, at least if possible having the hilliest or flatest routes possible maybe ?
