And btw, it's worth mentioning that in JupyterLab, we just merged a PR that will make embedding the Monaco editor (the editing component of VS code) much easier: https://github.com/jupyterlab/jupyterlab/pull/1140.

With that in, now the Monaco integration is being worked on: https://github.com/jupyterlab/jupyterlab/pull/1382.

We all want stronger editing capabilities, but it doesn't make sense for the Jupyter team to get into the business of writing text editors (plenty of better folks doing a great job on that already). So we're just trying to make it easier to integrate other text editors into the everyday workflow.
