Ask HN: How would Jupyter Notebook look like if created by Apple?

Jupyter Notebook is a great tool. I'm using it every day. I'm even building tools around it - to make notebooks sharing with non-coders easy.

Sometimes I found JN hard to use. The biggest pain is installation and package management. It can also have a more modern look. I'm wondering how would JN look like and work if it was developed by Apple (known for great design).

Do you think JN can be improved?
