feature request: approximate a route by a track

[routeconverter]

Another feature request: would it be possible to protect waypoints so they would be maintained during a remove operation? I usually give descriptive names to the waypoints I use to plot a route. If I then insert the intermediate waypoints and use the delete function to get a less dense set I usually also lose my own waypoints with descriptions.

I'm a bit clueless.... how do you think this could be implemented?
