I really like this application so I cannot stop thinking about new features which, in my opinion, will be useful.

In the first place, used as a car gps, I really think it should change zooming depending on speed as I don't need detailed maps when I'm driving fast on a motorway, while I do really need all the detail in the middle of the town. Of course, this feature should be turned on and off on demmand on the preferences dialog, as I'm sure not all the people will like it :-)

I would like also having some trip info on the map screen as current speed, heading (don't ask me why I like it so much), trip distance, altitude (maybe you can get all the other data from the car itself, but that isn't true for altitude) and the like.

The last feature (for the moment) I think could be quite useful is a waypoint database with "relevant" places with their GPS coordinates, and an on screen display of straight direction you should follow to get there. Sometimes, when you don't have any other better indication, this proves to be of much use.

What do you think?

I hope I will have some time for coding so I would like to be contributing code in the future.
