VIP Contacts Merge
For instance, John Doe has two seperate email addresses and therefore has 2 seperate listings in the VIP Contacts section of the side bar. I'd like the ability to merge these to one VIP Contact named John Doe which accesses both of his email adressess.
This should be built-in and tied to the contact. All email addresses associated with a particular individual are already grouped in my Contacts app. Airmail for OS X would also benefit from making this more sensible.
