From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I remember Okular having a decent set of features. It might be worth checking out. The webpage says it supports digital signing, which is a suprise to me because that's always been a hassle on linux for me. https://okular.kde.org/
I didn't realize okular supports a lot of other formats. As singular user I think this fits my needs. I'm especially interested that it can view .md files as well as open cbr and cbz files as well.
I was also gonna say Okular. It does everything I need it to do and more. Digital signing when I used it recently was pretty simple.
