Contacts can have so many different address, but I do love the standard Address Field, because it eliminates typing mistakes from people filling out a form.
Would love to see this back in Custom Fields for Contacts, Objects, Opportunities, and Business Fields.
Think of all the address that people collect; home address(es), office address(es), billing address, mail address, service address, event address, or even the addresses you need to give from doctors, dentist, etc. at the admission form of a daycare.
