This small plugin moves all scripts (including jQuery) to the footer to help speed up page load times, while keep stylesheets in the header. Note that this only works if you have plugins and a theme that utilizes wp_enqueue_scripts correctly.

This plugin is useful if you have want to enable your users to insert custom CSS or add custom headers or some JavaScript into the site without having to edit any theme files. Unlike similar header/footer plugins, this plugin by design does not allow to insert PHP code and does not contain any evil eval() calls.
The plugin is safe to use in WordPress Network installations, where site admins are not supposed to have PHP execution access but any HTML/CSS/JS code is safe to accept.
