Most of it seems like just short clips for your own personal reference. You aren't trying to teach anything, so kind of seems pointless (no offense). Putting tabs on them would change them completely since now you are teaching others how to pull this stuff off. I'd like to use some of the exercises, but I'm not going to bother figuring out the notes myself, call me lazy, but I'm sure most people would say the same.

Average length is 15 seconds and there are a ton of videos. If you go with the lesson idea, maybe you want to combine a bunch into 3-5 minute videos that all relate to each other.
