To anyone using it, I fixed the script by using rawgit to serve the CSS files. If you loaded the tool after I fixed the script auto update url info, it should update automatically. Otherwise, remove the script from your TamperMonkey/GreaseMonkey dashboard and click this link: direct link to raw script
Then tell your user script manager to install the script again. Refresh the page and everything should be working once more.
Since I updated the script a while back with the update url for the script and pointed it right at github, it should occasionally update automatically (or manually if you tell it to). So you won’t have to uninstall/reinstall again.
