User reviews

I've been using this for years now and I find it to be an invaluable tool when testing site usability/accessibility. The ability to provide an enormous coloured boarder that follows your focus target helps illustrate tab orders to clients/other developers and is an incredibly helpful teaching tool. My only complaint is it's not on other browsers! I'd love to see it on Firefox and Safari.
