My problems with Create Course which I use in Custom Drawing Method:
- Garmin maps are not as accurate as komoot, ridewithgps, plenty of data is missing like official tourist routes or small roads
- editor is not as good as on mentioned websites, I just ran into issue that I have to start from beggining because of weird track creation process where create course draw some part of path and I deleted last point but path not returned to previous state
- editor in Custom Drawing Method lacks things like: all points list, arrows on path in which direction it goes
