I don't think I've ever reviewed an extension, but man, what a find. Thanks so much for making it. I get very sick of closing overlays and finding the little "x" in some corner of it or some light colored "close" link. They get sneakier and sneakier about making you actually read the overlay to find a way to close it. Now when I see one, I know right away I can click on the X in the toolbar and it will disappear. So satisfying.
