Yes, I really like it. I wish they let extensions access it directly but it seems they don't (yet, at least). I'm also a bit surprised more hasn't been done to distribute it separately as a command line tool as I think something like that would be very helpful. I have seen a couple of attempts to put a CLI wrapper around it but they are third-party and seem to not be well maintained or documented.

Some one up thread pointed out about:translations is where it seems to be hidden.

Also a fan of this feature. It's actually been around awhile but I think the Asian languages are a more recent addition.
