Doesn't cover Asian languages at all which is no good to me. It was also incredibly slow at appearing at first and requires manual selection of a language in order to work. What's the point of letting it access all websites if it doesn't auto-detect the language a site is in?

It is very good, but it could be a lot if I had any way to hide the upper bar and make it more discreet
