For the lazy, here's a screenshot (and apologies to my friends who showed up here):
Go check it out; I think it's pretty cool.
Not a ton to say, but here are a few interesting notes about it:
I went with the idea that the caller has to provide the dialog component. It just seemed dumb to bake in my own and likely you'll want to make it look consistent with the dialogs/modals/whatever in the rest of your app. So you provide callbacks to open and close whatever dialog you want. FbFriends just provides the content.
I really didn't want to build this. In fact, the Facebook SDK used to have this ability, and they dropped support for it. I wish they hadn't.
A lot of Quarrels Harris Port was consumed during the making of this library.
Oh, and Merry Christmas!
