[Question] What would you say for a small "bookmark shelf" in the reader? Make the extension compatible with Scrapbook, multicolumn and page turning.

[Wacek]

I know Firefox uses Pocket, but I am against sending everything to the external services, I prefer to store things locally, especially when I don't need the data on the go, only at home.
What I am thinking of is a small "read later" section in the reader, which would store incremental (tree like) links, or something similar organized speciffically and only for the texts to read.
For now, I am using bookmark folder called "read it later", but maybe it would be useful and faster to have something similar in the raeder itself?
My second suggestion is to allow offline reading (Firefox reader does not work offline), especially while using extensions such as ScrapBook, but i don't know if thats possible, just asking.
Another usefull option would be to allow multicolumn reading, and also - very unique I haven't been able to find any other addon nor stylesheet that would do this - option to turn the pages with keyboard or mouse clicking, not scroll them like everwhere else.
Anyway, thank you for the extension, it works great :)
