A new beta of the Chax plugin for iChat has just been released, and with it comes the one feature from Adium that I truly miss: a Unified Contact List!

Also new is the inclusion of a unified contact list, which displays all contacts from all logged-in accounts. It will appear automatically at startup on first run, but it can also be shown from the Window menu. You can’t yet add or remove contacts from this list, but it will immediately reflect changes made to the original contact lists.

Finally my AIM, Google Talk and LJ Talk buddies can live happily all in one iChat list!
