It is really good how the address fields will close up on e.g. a Sales Invoice when printed if an address field is empty. However, including the Contact Name in this is an issue. A lot of sites will want the Contact Name in a different field from the addresses. In fact, in the Sales Invoice, there is a label for Contact Name - but you can't select the data field separately.

Result: You end up with another part of the Address showing in your Contact field if the Contact Name is empty.
