I'm finally annoyed enough about addresses that autocomplete in Mail but don't show up in Quicksilver that I'm trying to do something about it. I found Mail's Previous Recipients window, which helpfully allows you to add new contacts to the Address Book, but if the contact name already exists, there's no way I see to add the email address to it, or even create a new card to be merged.
Does anyone have a solution for this, or am I missing something obvious?
Thanks,
David
