Include GPS Tracks
Google Maps and many GPS units allow the recording of "tracks" linking sites and waypoints. This would be a useful addition.
As would import/export KML/KMZ and maybe other GPS file formats
Actually, I'm working on a diy surface marker gps with u/w tether to a waterproof phone app to track position on GPS. (Think long river drift dives and knowing where your exit point is)

not sure i see your point as gps doesn't work underwater :)
