To everyone frustrated with notebooks, I urge you to check out nextjournal.com:

- Notebooks are automatically versioned

- You can reference and reuse parts of other notebooks immutably through something they call "Transclusions": https://nextjournal.com/nextjournal/transclusions

- The technology-stacks underlying each notebook are immutable, meaning that notebooks work on any machine (no "hidden" dependencies).

- You can explicitly reference other results instead of relying on global state, making execution order irrelevant.

It's currently in private beta, but people are starting to use it in production. (EDIT: You can sign up using the code curryon2018)

(Disclaimer: friends of mine are building this and I used to work on it in the past.)
