A fair amount of development has gone into the widgets and the rich text output. Startup time are slow (1 - 2 minutes). Please try it out and file any bugs in the repo:

I’m trying it, but just see “installing: containers, dataframe, text, vector” in the top right corner (now for about 15 mins), when I try `abantu.md`.

Also as a linguist, the Bantu language notebook looks _so cool_. Very excited to get this running!

Oh. That one doesn’t work cause I forgot to package the data file and the error messaging still needs work. It’s a port of this Marimo notebook:

> Explore data and build apps seamlessly with marimo, a next-generation Python notebook.

Fixed this so it would cleanup old notebooks - this was preventing some people from trying it out cause of resource limits.
