It definitely needs lane guidance (even google maps which technically is not a navigation system has lane guidance)

When you search for POI it should tell you how far (distance and time) off rout the POI is from your rout. (again google maps does that.)

Wase has problem with long distance. I travel a lot from Somerset NJ to Toronto Canada, and always have to wait at least half an hour for Wase to start working aside from several times crashing and not being able to do anything with phone because it crashes. This might be due to large amount of downloading and processing.

Offline maps would be a nice thing.
