I've been using it for a little while now. Not sure about the /click bongosbutton xx function but I do know that alot of the customization and such is now buried in the addons menu rather than a click on the mini map button and the bind directly to spell/macro functionality is gone from the version I use anyway. That was disappointing. I made the switch for the WotLK beta though and I've gotten used to it I guess.
