If you're a classroom teacher who's been using Khan Academy in your classroom both before and after the change, would you be willing to post your feedback in the post I made to accumulate teacher feedback on Khan Academy Reimagined?

(I'm just another user, and I don't know if KA will use the feedback, but I think it's worth trying.)
