Spec that I have in mind for the title of editors.

* If the item is complete, "edit <item>" e.g. "edit card"
* If the item is missing one thing, "Add <thing>" e.g. "Add phone number"
* If the item is missing several things, "More information required"

Does that sound good Bruno?

Assigning to Tommy for the remainder because he is working on completion messages for addresses.

SGTM!
