Wow, this is some really high quality piece of software that I did not knew it existed until now. Thank you for sharing it!
I don't really have a good, productive, use case for it right now but I really can't wait to try it out. It looks really user friendly, fast, responsive, has a CLI, and it produces some easy to version in git latex files.
A while ago I wanted to create my CV in latex from scratch and gave up after days of trying to get FontAwesome to work (I wanted brand icons and other nice things), so I switched to a setup where I have a HTML webpage that looks like a paper page, and using chromium headless to "print" it to PDF (only works properly with chrome as other browsers have CSS incompatibilities on PDF generation, never mind the bit fart Firefox is doing on android lol). I guess I could try to replace that setup with this tool, it seems to have a export to PDF/HTML and a CLI interface for exports. Fingers crossed all goes well and hopefully it's customizable enough for the job. This will keep me busy/entertained for a while :).
