Thank you so much! While I've just skimmed the material, this seems like a really high-quality course. One suggestion: complementing each section with a set of flashcards students could use for spaced repetition learning (e.g. an Anki deck). These could include both definitions of terms and explanations of concepts, with plenty of visuals. Normally, if I were to go through the course, I would write flashcards myself, but it would be faster for me and feel more complete if they were baked into the course.
