Facebook integration and Game Center

Just a question for anyone with iOS6 beta installed.

Given the new integration of Facebook and an apparently updated Game Center I'm wondering if they've improved the ability to find and add friends.

Currently it's very cumbersome having to either know a friend's username or Apple ID before adding them as a friend. It would be a convenient and sensible upgrade if it used friends' Facebook/iOS links and provided a list of suggested friends.

(Just realised this could apply to the Find Friends app as well, given that, again, one has to know their email address or ID.)
