I think we have to start a thread with feature requests for this app and gnuite will chose what he thinks will not overload the app. :-)
here are some ideas I have:
1. when you download by area, make a short size estimate and show how many free megs do we need for that area.
2. change the track point (or track line) color by the precision
3. an option to send your coordinates to a web address (if you are connected to net). To be able to set to send the coordinates automaticaly every few minutes or manual...

:-)
