I'd like to use the address field since I like the 'Map it' feature and it looks cleaner than single address fields. Unfortunately I can't:
For Germany I need only 3 field in there:
Street Address, ZIP, City
Since I can't hide the 4th field, I am unable to use it and forced to go with separate fields.
I wouldn't care about a 4th field like 'Country' if it was optional for the user to fill, but every address field is mandatory and therefor worse user experience.
