to add to these, ...i think this wud make the Search Feature a lot more useful, since u wudnt have to search individually thru the logs for each contact (will have to login to the client though)

The Buddy Pounce feature though excellent is not necessarily essential (to me atleast ... smile )
a simpler notification option ...like u said ... a "User is now online" toast box for certain users is what would be useful enuf...
