Wow this is cool since I was thinking of this exact problem a couple days back. My thought process was inspired by Loom videos where I thought a round head of the instructor in front of an interactive IDE would be a great way to reach.

My idea was to try to create a VS Code plugin for this when instructor videos, stitched with a Git repository would "play" inside the IDE.

Edit: The homepage of Loom has a good enough example to get the idea I had, just imagine the instructor head and the video controls inside your Editor. https://www.loom.com/
