I would like them to update all videos instead of using old ones with the new. Like some of the videos have Khan in them and he will make a mistake halfway through and then start over and we have to watch him draw stuff and erase everything vs the new stuff where it was basically a contest so only the best videos made it through. you can really tell the production value is pretty high on those videos and instead of 15 min they are like 5-7 since we dont have to watch all the drawing and writing and backing up because of mistakes.
