Just checked out live commenting feature on Observable [1], the ability to send code suggestions and preview + merge suggestion with 1-click looks amazing.

I built a tool [2] for Jupyter notebook code reviews which has commenting feature for GitHub pull requests (regular text comments). It would be great to have actual code edits/suggestions as review comments.
