Nice mockups :-)
I'll consider your requests..
1)For now you can swap the cursor graphics with whatever images you have, as long as it follows the same format...
2) I am moving the gps functions out of the main loop in the newer version, so when you move a cursor you don't loose the trip data
3) this is alot of work... perhaps eventually I'll look in to it... but meantime I'll probably just sort pois alphabetically...
