Nick,
Here is my wishlist... (don't faint)... ;-)
1. Ability to put the phone into "tracking mode only". My phone is sitting in the glove box of my car so I don't need to see the Google Map on the phone (or the extra data). The folks at http://www.instamapper.com do this and it works VERY well... I also like their raw text/GPS status display on the phone.
2. Ability to change the tracking time to a value specified in seconds. Right now the minimum is 1 minute... I'd like to track every 15-30 seconds for more accuracy in mapping.
3. Ability to see the lat/long of the cell phone tower (in case a GPS location can not be obtained).
4. Ability to see the battery life remaining on the cell phone.
I have more... but those are the top on my wishlist.

PS - I'm willing to pay money for those features. Does anyone else here want to chip in with me? Perhaps we can create a "bounty list" on here so Nick can make a little cash while he's implementing the most popular features?
