The Rooster Lingq extension supports watching YouTube videos like Language Reactor, but interfaces with Lingq to keep your stats and create lessons.
I have not used it a lot. I prefer simply listen to audio. It trains my brain to rely on piecing the language clues together without reference to a dictionary. But if you like a Language Reactor kind of tool and want to have your lessons in Lingq as well, this extension will do that.
