I really enjoyed your tutorial, but there is one feature that would make it much, much easier, and that is the ability to go back in time a small amount. I’m not sure if I missed the way to do that, but the only controls I saw in the lower left where play, pause, and stop, and right-clicking didn’t give me that option either. This would be very helpful because a few times I either didn’t quite get what you said, or something distracted me (like a cat jumping up on my desk, or meowing for attention) and by the time my attention was back on the tutorial, I had no easy way to see the last few seconds I’d missed, other than start over and sit through it again.
If you could either provide a timeline control, or a couple buttons to ‘jump ahead 10 seconds’ and ‘jump back 10 seconds’, that would make this even better…
Thanks for putting this together and making it available!
