Hi there. I think this code ==> is very userful, but, can be better.
How can I add options to choice from Profile / Settings:

[√] Everyone (marked by default)
[ ] Only friends

// Restrict Private Message to friends.
function pp_check_message_recipients( $message_info ) {

	//  Site admins are not restricted
	if ( is_super_admin() )
		return $message_info;
	
	$recipients = $message_info->recipients;

	$friend_ids = friends_get_friend_user_ids( bp_displayed_user_id() ); 

	$nf = 0; 
		
	foreach ( $recipients as $key => $recipient ) {

		if ( ! in_array( $recipient->user_id, $friend_ids ) ) 
			$nf++;

	}

	// If any recipients are not friends, remove everyone from the recipient's list
	if (  $nf > 0 ) 
		unset( $message_info->recipients );

	return $message_info;
}
add_action( 'messages_message_before_save', 'pp_check_message_recipients' );
