Vscode-jupyter: Jupyter Notebook: add access to cell metadata

[chrisjsewell]

Feature: Notebook Editor, Interactive Window, Python Editor cells

As an extension to microsoft/vscode-jupyter#1121, to access the full notebook functionality, cell metadata should be accessible to view and modify in some manner.

Thanks for the suggestion.

How do you access it now outside of VS code?

[chrisjsewell]

In Jupyter lab, the cell and document level metadata is available in the side-bar, which also contains controls for tags, and is interactive (i.e. you can type into the metadata boxes). This would be the ideal solution, but I'm not sure if this could be achieved in the VS Code view containers? If not, perhaps a partial solution would be a button to toggle between a metadata viewer and the current variables' viewer.

Thanks for the suggestion. We'll review this and get back to you.

This is essential for rendering notebooks into slides.

A simple solution for cell metadata would be to add the option to view and edit the raw json of the cell in addition to the current markdown/code options.
