After working a bit with this earlier and now have played with it a bit more since that "public" alpha release. The new address is better but still lacking.
The better: previously i entered a new address of 123 My Street, My City, My State and it would return a few entries, the closes of which is My Street, My City, My State omitting the house number, 123. This has now been fixed. Thanks.
The lacking: Please add the ability to look up contact addresses. This will save having to manually enter all this text information. This will be very useful for me, since I always have my contact list updated to most known destinations.
Another nice to have would be a integration or some sort of link to other inputs. Say a search from any location results in an address. clicking on the address will invoke some intent/event listener that identifies that this is an address. and to send it to waze. I've seen something similar to this for the default google maps where it displays the address in the application.
