I'm still convinced, we need:

• extra fields for first and last name
• extra fields for zipcode and city
• extra fields for prefix and phone number

• add fields for P.O. Box (with extra zipcode and city)
• add field for country

would make streber more powerful in CRM. And would be easier to synchronize with adress managers (Exchange, Outlook, ...) in the future!
