The mobile app needs to have an option NOT to snap the map automatically to the current position. It is SUPREMELY annoying to be looking around the map and then find that it automatically snaps back to my current GPS location. In fact, it seems obvious to me that the app should have this option.
A user will often want to scan around by hand, such as when stopped at a light, or prior to making a trip. The target icon allows one to snap back manually at any time.
