custom CSS plugin

I remember reading several threads here in this forum about different CSS editors, also drmike, mentioned he used a custom coded/changed plugin and today I stumbled upon something that looks like automatic is finally releasing their custom CSS plugin:

please correct me if I am wrong, but that is how it looks to me although in typical automatic manner, there is so little description for that plugin, I am not even 100% sure this is what it does :slight_smile:

If anyone finds one of the older original threads about custom CSs editor, feel free to move my post...
