When I address e-mail in Mail.app, I'd prefer to type initials like "spj" to address a message to my good buddy Steve Jobs, "joe" for my friend Joseph, or other nicknames for the others I e-mail regularly, rather than having to type a prefix of their name to use the auto-expand feature. I know a lot of Steves so typing "Steve" isn't efficient, and I think of Joe as Joe, even though he likes Joseph used with his e-mail address. But the auto-expansion feature in Mail.app doesn't seem to work using the "nickname" field (or Notes or other fields that I have filled in) in Address Book. This seems like such an obvious feature. Am I missing something? I have the "Automatically complete addresses" option on, but I don't have an LDAP server, just my little old Address Book full of names.
