Very nice so far, Andreas. Good job in showing step-by-step how to create a lesson. The captions are an especially nice touch.
Suggestion: A teacher may not know what the lesson mod does, what a branch is, when it is appropriate to use the lesson mod vs the quiz mod, etc. It would be very good if you would add some helpful information for a teacher who is new to Moodle. That would make your movie much more useful.
I look forward to the next version!
