Hello eCoach now uses new map widget which allows all kinds of new features. Adding previous route for comparison could be implemented someday... but for now im still concentrating on getting all basic features in place for Fremantle version of eCoach.
wont be continuing support for legacy versions of eCoach, so i suggest you to wait for new maemo device when it someday comes out
Or maybe fremantle version of eCoach can be run on Mer, i dont know...
