JupyterLab 4.0: a development environment for education and research

I think autocompletion has improved since 2018, there are plugins for linting, and there are ideas floating around for managing dependencies (but they are unfortunately not catching on, from what I know). Some of these issues would not be solved by the project but maybe by other people in the ecosystem.

He also focuses a lot on four code cells being executed out of order. That's not great, but it's a very minor issue in any of my notebook usage. If I can't use the restart and run all button repeatedly, I have a problem and I fix it.
