Probably expecting of suggesting a feature as shown here ? See the you tube video in the link.
I created this post as a comment from Feature request list and see that the feature request no didn't come along.
This is a user question on feature request no 30, https://www.plotaroute.com/featurerequests?ID=30
It's looking like this feature request is not that asked for and I can understand that, but do someone of you plotaroute users use another tool (win or web) to create routes on scanned maps?
I'm really longing to find a solution to create a route with directions/course points on a kmz/kml-map and then import it to PlotaRoute to finalize it and export to my fenix watch.
