Drupal 7 Views output changes by QueryPath
<?php
// Moving lots of stuff (filters, counters, headers...) around in a View
// using QueryPath.
// Not quite the most Drupal-like, but actually much more reliable when it
// comes to inserting items into filters that are not covered by the Views UI
// and moving counters out of the header.
/**
* Implements hook_views_post_render().
*/
