Custom CSS by Denis

A way to quickly toggle custom CSS for each site?

It's a good extension, just wondering if it would be hard to add a toggle switch below the textbox to toggle the custom style for each site? For some domains I only want to use custom CSS on specific pages, so that would be a nice little improvement. I know I can just add comment tags but that gets a bit tedious after a while. If this gets added I'll give it 5 stars for sure.
