Description

Feature: Notebook Editor, Interactive Window, Python Editor cells

Description

The unofficial Jupyter notebook extension have a "Freeze" extension. I am wondering if the team can add this feature to the notebook extension. It has 3 modes:

  • Unlock: user can freely edit and execute the content of the cell
  • Read-only: user can execute but not edit the cell
  • Frozen: user can neither edit nor execute the cell

Use cases:

  • Run the entire notebook from end to end, but want to skip some cells
  • Store some core functions / parameters at a cell, and make that cell read-only to avoid changes during model tuning

Note:

Research direction
Investigate the Jupyter contrib nbextensions freeze extension and the VS Code notebook API. Look at relevant files in the VS Code repository, particularly under src/vs/workbench/contrib/notebook/. Review comments for any maintainer feedback or design decisions. Focus on understanding how cell metadata is currently handled and how to extend it for freeze/protect/collapse functionality.
