As I recall, adding to the Contacts list from the Call History doesn't work properly anyway. If you receive a call from an existing contact who is using a new "Location," the tool will not add the Location to the existing contact. Instead, it adds an entirely new contact, which results in duplicates.

What I would really like to see is the ability to import to and export from the Contacts list, using CSV or a similar database format. That way, I could arrange the contacts the way I want, or I could adapt the list from an existing Outlook or Google contacts list.
