Super happy to see this announcement. I have been considering making a super-simple read-only *.ipynb viewer for the console in Textual for months now.
But voila! The cool froods over here have done one better. I am not the only one wanting this...
Just like JupyterLab, jpterm now has a top bar in the notebook editor. In the future it will have buttons to run cells, interrupt execution, restart the kernel, etc. But for now there is only the kernel busy indicator. Still, I think it's kind of neat 😄
