This add-on collects javascripts in post-view output and moves them to the bottom of the page. This has a noticeable impact on page-load times as pending HTTP requests postpone rendering of a page, while scripts aren't run anyways until everything is loaded.

This add-on requires PHP 5.4+!
Trying to install it on earlier versions will break your forum.
