nov.el VS org-remark

bddean's ereader and nov.el look appealing, especially with nov-xwidget.el for formatting on the latter.

I'm one of those weird users who works in both, and I've also never really understood the need to pick a side. I initially used emacs for years, and now I've used both for years. I also don't pick a side in the tea and coffee debate, sometimes I want rooibos and others espresso.

Admittedly, my emacs usage at this point is largely to treat it as a collection of distinct apps; fire up in nov-mode¹ mode to read books, fire up in magit-status² to mangle git repository, etc. It really feels like there are a collection of best of breed apps that just happen to built on emacs as a toolkit, most of which are fully functional without buying in to emacs for life(not that I'm saying there is anything wrong with that).

The only time I really use it as an actual editing tool is when I'm working on documentation, and that is largely because I like being able to see inline screenshots in that instance.

It has been considered and rejected due to the inherent complexity: https://github.com/wasamasa/nov.el/issues/4

I use something similar, called org-remark. By the description of both, they seem to share functionalities. Just mentioning it for visibility :)

org-remark hits some of your requests, but I think lacks the git parts in point 3.

https://github.com/nobiot/org-remark might also work

There is also Org-remark, which lets you highlight and annotate any text file using Org-mode.

Also if you're annotating plain text, org-remark is great. I love not having to use the mouse to select text.

What happens when line number changes? For example https://github.com/nobiot/org-remark handles this changes, but can only anotate org-mode files

Org-Remark, for plain text files perhaps.
