Works

This plugin works for me.

The below issue is (or is about to be) fixed:
<s>I’ve rated it three stars instead of five stars though, due to a bug which I describe below. If you let me know when the bug is fixed, I’m happy to bump my rating up to five stars.

There are two instances of wp_register_script() in the plugin in which the arguments appear to be the wrong way around.

The codex indicates that this is the correct order:
wp_register_script( $handle, $src, $deps, $ver, $in_footer );

But the plugin uses this order:
wp_register_script( $handle, $src, $ver, $deps, $in_footer );

I’m guessing this will cause the plugin to break on sites which don’t use jQuery and it causes a PHP error to display, due to it attempting to read an array as a string.</s>
