Thanks. I gave Vroom a try, but it barfed with “Unfound locations”.

Actually, I had something much simpler in mind: The software should just take the GPX (KML, really, since GMM doesn’t export as GPX) as input, and provide a router that I could use to manually build routes between the waypoints, so it’d be lot easier than the “travelling salesman problem”.

Oh well, I’ll keep doing it the harder way, namely

  1. keeping the Google My Maps open in one tab,

  2. drawing a route in a second tab, switching back and forth with (SHIFT+)CTRL+TAB

  3. exporting the route

  4. importing the route in GMM

Thank you.


Edit: Done.
