iMessage Contact List in Messages Beta for Mac
I downloaded and am exploring the iMessage features in the new Messages Beta App for Mac, however, I've noticed that there is no "buddy list" or easy way to see who else in my contacts I am able to send an iMessage to. Of course I can think in my head who I know with iPhones, iPads etc, but even then there isn't a way to tell if they even have iOS 5... shouldn't there be an iMessage group in the contacts list?
