Yes! Every now and then I give JupyterLab a go but I keep going back to classic notebook. The only two extensions I need is Vim key bindings and Black formatting. I might checkout version 3 in a few months, but classic has a “feel” that just works for me. I’ve also tried the VSCode abs PyCharm notebooks. The dealbreaker is always how it displays the output of cells. It sucks compared to classic.

Then you might be interested in a new project called JupyterLab Classic, an alternative JupyterLab distribution with the Classic Notebook look and feel: https://github.com/jtpio/jupyterlab-classic

Once the vim and black extensions adopt the new extension distribution system, they should also be compatible with JupyterLab Classic.
