> 'm a fan of Manuskript on Linux. It's similar but has more features and, IMO, looks better: https://www.theologeek.ch/manuskript/

It's hard to tell about "looks better": the link for "screenshots" takes you to the #team anchor on the page, which is actually the "latest news" section.

The "How to use" link in the download for 0.17 takes you to https://sourceforge.net/u/gedakc/profile/

This does not inspire confidence :-/

Better documentation (well, actually, more like documentation at all), 100+ contributors, 10 years of contributions.

There's a lot of general hand-waving about its featureset and whatnot - and an odd jab about non-English support - but no explanation of how non-English language support is lacking in other projects and why hers is better. And am I really supposed to believe that her project has better non-English support than than something that has 100+ contributors over ten years?

Cheese Paper is written in rust. That's reason enough to give it a try. Manuskript may have more features if you need them, but it's written in python+js, and has a more obtuse file format.

There's also novelWriter which is also python but at least it uses pyqt.
