Hi, I have been watching your videos and think you can improve some things;)
It is correct place to create this topic?
Player:
- video speed doesn’t saved when video changes
- if video finished, I use keyboard to go left, but you have timeout that redirects you to next video. You can add if any action, finish timeout.
- if I use settings menu, then don’t close it and click on video or fullscreen (F key), menu doesn’t closed.
- maybe add video hotkeys instructions for students

Wrong instructor.
Quizzes:
- better to have persent of correct answers after finish the quiz. Or we may skip some understanding.
- add keyboard support (navigation between answers, enter submitting).
If you will need some more explanation, just ask 
We are (students) will have a lot of time with you, better to use things as convenient as possible;)
