Website: losing filename when loading kurviger and GPX files

Hi,
we discussed that in

but I think we did not consider this case - at least I am sure I did not!

I think the proposal above is very good: The last import of a file as route defines the name proposal for export function.

There is the same topic for the app - should we open a separate thread for the app? @Beemer: Could you tag it as app also and perhaps change the title?

Regards Markus
