Thanks for the example! That definitely includes a bunch of things I think Jupyter should have, but "purists" might consider out of scope (theming, ToC, something as simple as being able to hide cells interactively). Currently, Jupyter works well for development, but the result is often hard to read because code gets in the way. (unless you use nbconvert, but that sometimes defeats the purpose)
