Minimatica WordPress Theme: Removing the 'View all posts filed under'

Thanks to the tip from konstruktors.com this is how I was able to remove the 'View all posts filed under' line which hovers over the link categories. It's not included on their page, but since it's a php file, you need to have start and close tags.  Here's my mod:

<?php
add_filter('wp_list_categories', 'remove_category_link_prefix');

function remove_category_link_prefix($output) {
return str_replace('View all posts filed under ', '', $output);
}
?>
