Thanks for trying out guys and glad you find the app somewhat nice.
Thanks for finding this. I've done some testing last night and it seems this is a problem only on the HD2. Tried on HD2 and also the Omnia 7 and HTC Mozart. Current location was reported correctly on the other 2 all with GPS, mobile network and WiFi turned on. I'll definitely look into this issue.
If route detail means turn-by-turn itinerary list for the route, it's definitely coming in the next version. Google Longitude is an interesting idea that I've never thought about. I should add this to my "To-Investigate" list now
I'm quite interested in the bugs that you encountered. Can you let me know which handset your are using? And if possible, how much disk space you still have?
About the 'me' pin, I don't like it either. That's one of the first changes I'm gonna bring in the next version, making the 'me' pin editable like the other pins and, you're right, I should give it a nice icon too
