Thanks for this plugin - it's great and just what I was needing.
Only thing I found (and not critical anyway) - is the scan doesn't refresh the plugin page when it's finished running - the please wait and throbber stays visible.
Manually refreshing the page brings up the result of the scan though, and everything else then works.
This could be something with Ajax perhaps? or the server setup.
I've installed the plugin on two sites on different Apache servers (Afrihost.com and GoDaddy hosting) with the same result. Both using WP 3.4.1 and plugin version 0.1
I clicked It Works and gave it a deserving 5 stars (and 9.1 on my own review - http://tech.graphicline.co.za/jsdelivr-wordpress-cdn-plugin-review/)
