Played a little more with Open Mapquest - no option to edit created route. Looking for some more options then…
p.s.
GPSWandern is off - doesn’t stick to roads, just draws straight lines (or at least I couldn’t find the option).
p.p.s.
GPSies looked really good for this thing until I realized that when I set two points I can’t refince the route by adding additional one between them…
