I'm happy to see people are interested in the editor! Let me also point out that I wrote a short blog post about the motivation behind quiver, as well as some of its key features, here: https://varkor.github.io/blog/2020/11/25/announcing-quiver.h...

This tool is fantastic! I was able to generate a Fourier-Poisson cube [0] in about 10 minutes, and the UI is incredibly intuitive. The focus on commutative diagrams, rather than a free-form canvas, is a brilliant design choice that keeps it clean and easy to use. I wish I'd had this during my thesis; it would have saved so much time. [0] https://q.uiver.app/#q=WzAsOCxbMCwxLCJnIFxcdGV4dHsgb24gfVxcb...

This project offers a convenient way to generate commutative diagrams and export them to tikz-cd; I thought the very well commented code might be interesting to people here.
