Suggestion: add a "export as link to GPX".
Rationale: exporting through USB is so very 2005, but all currently available alternatives require the use of intermediate storage.
Current "export as a link" links to the interactive MRA webapp. While I understand the viral value this has for MRA (as a company), as a user I would like to be able to drop a link directly into other apps.
This is what URLs were invented for, right?
