A merging contact feature would be a GREAT improvement, since sometimes people use different IDs in social networks like twitter and facebook, and the contact manager apps aren't efficient in recognizing who are who.
I've been managing (merge) my contacts using the native contacts app and GO Contacts (not that good in this item), but this isn't practical.
