Apropos of nothing, I gotta say that Typst looks very attractive and promising. I’m happy and locked in right now to to my Scrivener+pandoc+pandoc-crossref workflow. But that just means I can let the Typst team keep doing their thing and give it a try after it develops a bit further. The big downside from my perspective is that it doesn’t use LaTeX math. But I see from the pandoc forums that there’s a pandoc-friendly converter in the works.
EDIT: I think I’m seeing that Typst outputs to PDF only, which is not great if journals etc. require Word submissions. Still, I’m interested in the project and curious to see where it goes.
