So interesting to see something like this right after vscode added jupyter notebook support this past month, which I was excited to see given how poor the editing experience is in standard notebooks, especially around intelligent autocomplete.
There are lots of cool developments in IDE notebook support - IntelliJ just dropped a plug-in for it as well. To be honest I'd be thrilled if an IDE solution could fill all the gaps that Polynote's targeting (our work would be done!) so I'm looking forward to seeing what develops.
