Since at least a few of you use this addon with UI.X:
The addon broke with the newest UI.X version (1.5.3).
I modified the addon to work with the newest UI.X version (it also works with any other theme).
Simply upgrade your existing version with this version:

Note to mods/admins: If this isn't allowed, please delete the post, but since the original developer wasn't active for a long time it would only be fair for UI.X users to be able to use this addon.
