Another comment also mentioned search, although they meant searching for the content on Google but it applies to manually searching through the course content after you’ve completed it when you need to go back and reference something. I’ve had to do that recently and it really helped that the course was divided into small chunks with very specific focus and relevant titles. I also agree that being able to watch short 10 minute videos is much better when you’re trying to fit a little learning into a busy schedule. It means I can do a few before work, at lunch or whenever I have a bit of extra time.
