I use addresses a lot. Nimble adds all kinds of incomplete addresses to the list of addresses for a person or company. These sometimes show up above a correct address I have verified, making them 'address 1' in an export.

Add a check box next to an address to lock an address as a main (top) address for the address type that does not get updated by Nimble. Nimble can still add all the bogus addresses, but they won't be picked as 'address 1'. There could be a main Work, Home and Other address checked

The same applies for phone numbers. If I verify a number I want to be able to lock it in as the main number for the number type (such as the main number for the Main type) and I want that number to be listed first, at the top of the list.

(Actually, I would very much like to see those addresses NOT get added at all if they don't have a) a non-empty street address field AND b) a non-empty zip code)
