> '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 :-/
