[Plugin: Social Author Bio] Customization without getting in trouble in future versions/feature requ

Hi Nick,

Thank you for this wonderful plugin. I did two things but I’m not sure it’s the best way to do them without getting into a hassle during an upgrade.

1. I changed avatar size. In social_author_bio.php on line 981, I changed get_avatar( $ID, “80” ); into get_avatar( $ID, “140” );
2. In multisite installation. Every author get their own personal blog(strictly one author per blog.) I want author name/avatar link in bio box to point to his homepage; ie mainsite.com/his-blog instead of mainsite.com/his-blog/author/his-name. starting at line 1000, within display() function, I added %home% in $token array and a correspoding get_home_url() in $replace array(code below)

   // Search
   		$token = array (	'%avatar%',
   					'%prefix%',
   					'%name%',
   					'%author_link%',
   					'%post_count%',
   					'%author_desc%',
   					'%socials%',
   					'%home%');
   
   		// Replace
   		$replace = array (	$avatar,
   					$options['prefix'],
   					get_the_author_meta("display_name", $ID),
   					get_author_posts_url($ID),
   					count_user_posts($ID),
   					get_the_author_meta("description", $ID),
   					$this->social_icons($ID),
   					get_home_url());

What is the best way to implement those changes for smoother upgrading process? Also I’d like to request these features to be added in future releases options/customizations. I’m a novice in PHP; your guidance would be greatly appreciated.
