I have always wanted Kindle to support a lot more features than what it does today. Digital books could be a lot more than what they are today. Want to embed a python REPL in a python book for users to test things right in the book, from a common source? Want to embed function graphs in a Math book from a common source? How about a theorem prover right there in the book? How about a Wolfram engine embedded in there to solve arbitrary calculus problems? How about a section in another book - license it from the other publisher and embed it into your book? Embedding a video, a web page, a 3D visualization engine, etc should all be possible in a digital book. Looks like this maybe able to achieve all of this. Just need to get Amazon Kindle team on board with this.
