I think many people including me want to have the Japanese translation option for websites. I need to use now google translate for translating Japanese websites. And I don't like it to use every time google translate for that.
I was very excited when the new translator came with 117. Only to find that it can only translate like 2 languages in a trench coat. Nothing wrong with starting with a small scope, far from it, particularly when you are working on something as complex as a client-side translator, but it would be nice (really nice, actually) if the tab where you install new languages had a roadmap of what languages are coming and when to expect them.
