Hello,
One of the great features of Cycle.travel is being able to draw a route and download it as a file without having to first save it onto the server, which requires registering + logging on.
I suggest adding a feature: Make it possible for the user to type a name that will then be used by the server as file name + "<name></name>" field in the file, as a more explicit alternative to the current "cycle_travel.gpx" and "<name>cycle.travel</name>", respectively.
Cheers,
