I also prefer those lessons do not go automaticlly forward. It's confusing because it skips to the next lesson each time you click on BEGIN. I would rather do it when I feel I am ready for the next lesson and not rushed into a next one all the time.
A simple poll would do the trick with people voting there preference/ But this is definitely one of those annoying changes that should not be there as it messes with the natural speed of learning of a learner. You shouldn't be rushed like that + it's just wrong that it skips every time to a next lesson with each press of BEGIN. I fight with it daily learning a new song/
