Thank you. Would Jupyter be a good comparision (though that isn't prose-oriented)? Maybe even Emacs? What users are you targeting? Developers usually don't need to write a lot of prose.

I'm always interested in systems that are willing to make the tradeoff of more power and sophistication at the cost of a greater learning curve, and I strongly agree that we need something beyond PDFs and webpages (and Word documents). Nota interests me but I'm having a hard time seeing how the power and sophistication will significantly improve my writing or documents (and I don't develop React applications). A use case would be great; the hyperlinks and tooltips on the page I see can be done much more simply.
