Recent Contacts - merging with My Contacts.
Recent Contacts are created on the fly from incoming emails, useful. My Contacts are usually created on a phone and sync'd back to names.nsf. In practice the phone contact rarely has the email address and to merge the two would be a big advantage, however as the email address is used as the key a second contact is created on merge. It would be really useful to pop up a dialogue box offering near matches based on name as options to merge into.
