Navigation App

So first off I would like to say i am impressed with the free Google Navigation App. The visual display is nice and the auto-correction, if you make a wrong turn, recalculates quickly which is something the old Verizon Navigator really stunk at doing. HOWEVER, the key to not missing the turns in most cases is knowing what lane you need to be in. I find this app does not give you a heads up notification of what lane you should be in prior to it telling you to turn right or left. I have found you have to rely on the digital display and look at the way the map turns in order to try and 'figure' out what direction you should be going in. pretty dangerous as you should keep your eyes on the road.
Not to mention, that i live in NYC and trying to determine which way the arrow is pointing when the map is cluttered with over passes, numerous highway interchanges, wrap arounds etc its becomes difficult.

Is there a site that this message can be posted on? I know google is all about being open for developers. Maybe this function can be added in as an update to the Navigator?
