When saving a ride after logging with the phone app (I'm using Android), it would be helpful if the name / filename field was pre - populated with a name.
My Garmin GPS units fill in the date/timestamp as the suggested filename. (So I'm stealing this idea from them.) It's also in overwrite mode so I can start typing a new filename if desired (I've never done this, I usually just go with the timestamp).
At the end of a ride I'm usually not in the mood for typing so i just give them one-letter names like "N"!
