I see someone is working on getting Foliate fixed up Debian. They're a lot better than I am in getting rid of all the problems that lintian turns up, such as copyright notices and having javascript stuff rebuilt from source rather than using the files that Foliate provides.
I did package Arqiver from scratch for MX today--it's a Qt-based archive manager from the Featherpad and Kvantum developer. It would go great with a lightweight Qt desktop like LXQT or Lumina. It works a lot like Ark on KDE.
