Actually, I should include this as an option on the plugin. Right now the code looks like this:
$info = '<a href="' . get_permalink($single->ID).'" >' . $single->post_title . '</a>';
So this generates a simple link:
<a href="https://wordpress.stackexchange.com/questions/44467/yourpost.html">Post Title</a>
I’ll see what I can do on a next version to make this customizable, but in the meantime you can go to line 164 on /include/CatListDisplayer.php and change that line into something like this:
$info = '<a href="' . get_permalink($single->ID).'" rel="bookmark" title=". $single->post_title . ">' . $single->post_title . '</a>';
