The state dropdown add-on is moving the country (billing and shipping) field just before the bfirstname/sfirstname.

Not always the desired behaviour. Sometimes you just don't want to move the field, or move it somewhere else.
That's where these 2 new filters comes in handy.

Filters:

pmpro_state_dropdowns_bcountry_before_field
pmpro_state_dropdowns_scountry_before_field

Usage:

Don't move the bcountry field

add_filter( 'pmpro_state_dropdowns_bcountry_before_field', '__return_false' );

Move the bcountry field just before the bstate field.

add_filter( 'pmpro_state_dropdowns_bcountry_before_field', function( $fieldname ){
	return 'bstate';
} );
