1) It would be nice to be able to perform route planning from waze.com. The user could login to their account and plan routes then when they use their waze from their Android or iPhone they could receive the route.
2) Additionally it would be nice to be able set all of your preferences through waze.com login. A user like myself has the waze app built into my car so I can only adjust settings and route planning when in my car. If I could do it from anywhere with a network connection that would be great.
