Agreed - thats the vast majority of my recently used addresses.  ignore/flag/highlight/report the rest.  Or just put the entry - which is an e-mail address - in the book by itself.

In addition to having a longer recently used list of addresess, I'd like to see an automatic copy/update of the REU items right to the main address book.

This would only be useful if the email address was of the form "display name"<email address> so that the address book would have a lookup name which it could then associate with an email address.
