Hello,
I have a suggestion for the Download dialog that is displayed after the user has clicked on the GPS button to download an unsaved route: Add a Name field, which will be used to name 1) the file (instead of the generic cycle_travel.kml and 2) add the route in the <name>…</name> section in the file proper (and thus, will be displayed in the phone).
The alternative is to first save the route (and get a /123456 URL), but it's cumbersome for just a one-shot.
Cheers,
