I would like to see improvements in the following areas in the introductory lectures. 1. 'As you know' - I don't know. I've used Photoshop or Illustrator, but it would have been harder for someone who doesn't even know that. 2. Using shortcuts without explanation - Something is happening on the instructor's screen, but I can't tell what I pressed. Even if it's a shortcut that I habitually use, please explain what I pressed every time during the lecture. 3. 'Do this' - I'm curious about exactly where to click/drag to get what effect, and I don't even know what the function is called.
