Simple GDoc style commenting for notebooks (outside of diff/PR/commit context)

Problem

Sometimes you are looking for peer feedback on the finished notebook & incremental edits to reach the final state are not important (i.e. diff is not useful/required).
A lot of small teams directly push notebooks to master branch where each member is working on their own set of notebooks.

In both the situations, pull requests are not a part of the natural workflow. Can users still get their notebooks reviewed by peers without worrying about pull requests / commits / diffs?

Solution

User can browse their repository on ReviewNB, open a notebook & start a discussion on any notebook cell. Something like Google Docs or Google Colab (screenshot below),

Open Questions

Where would comments be stored?
What happens to comments when the notebook changes (e.g. cells with comments are deleted/split)?
