two feature requests

[routeconverter]

If you could add the "show on map" checkbox and a undo/redo option I think that would be very help full in the decimation of tracks. Would it be possible to show routes on the map with a certain degree of transparency?

It is possible but currently I'm limiting the number of positions that can form a route to 22 segments of 42 positions. Adding "show on map" checkbox means I have to divide this number by 2,3,4,5 for each route displayed.

And is the geocode problem with the google maps URL solvable?

As long as only Google knows how to decode the geocode parameter: no. Here is a workaround.
