Great tool!!! Rated 5 out of 5 stars
I just started using this tool on a friends recommendation for editing styles in Stylish. Its the biggest time saver and headache reducer.
My only complaint is that when you are viewing "CSS style rules", you cannot right click or highlight and copy the rules. Please please please fix this. Its great that "property and value" are copyable because it save a lot of time but not being able to copy the rule is the biggest pain in the butt ever.
Great addon that I never needed until recently!!
