"Pretty plugins" is non-responsive?

I am very surprised this plugin is not responsive. The entire wordpress admin is responsive and this plugin is not. The boxes move and they're still viewable but does WPMU DEV has plans to improve this? Its just CSS but I am trying to provide my users with the best environment possible and the way this plugin is displayed does not meet those standards although the functionality is outstanding .. would be amazing if both the functionality and layout were hand to hand! Please let me know if this will be corrected. Thank you
