How to show more than one track

[routeconverter]

Your advice is some kind to achieve my purpose. A little disadvantage this technique is all the tracks have the same colour.

There are two main limitations currently in RouteConverter that get in the way of a simpler solution:

• it's map implementation is designed for just one position list and extending this would be a big task
  
• I haven't seen a simple user interface interaction yet how the user might decide on the color of parts of the track
  

Any help is appreciated.
