[jitsi-users] Buddy groupping annoyance

We do not use groups in the contact lists as they take too much extra space (not just with Jitsi, but with any XMPP clients).
Jitsi creates a new group NotInContactList when a new JID contacts the user. We've been trying to get rid of the new group but it looks like we can only delete the user and re-add by searching for their JID. Is there another way to move the new buddy out of the autocreated group and then delete the group?

Thank you
