Hi,
Currently, this plugin only supports local file, it is a good idea to include the remote files, hopefully, I can add it in the future.
Thank you for your suggestion, I have removed the var query strings from the CSS and javascript file URL.
I have updated the plugins, in order to easy to maintain I have made a significant change to the plugin files structure, so, if you encounter a problem during an update, please uninstall and then re-install the plugin, sorry if it makes you inconvenience.
