Hey, it looks like ipywidgets finally work in VSCode notebooks! Light/dark colorscheme clashes that would make Star Wars proud, but I'll take it.

Pyviz (panel, holoviews, etc) interactivity doesn't look like it works yet. Ipywidgets might be enough, though!

JupyterLab has had debugging for a while. It seems to be broken in both VSCode and Jupyter, though (or, rather, it hasn't broken on the breakpoints, where it ought to have broken). Ah well, probably needs more futzing around with the kernel.
