MuPDF feature which might interest you

Hello crew.

I was very missing a feature which would remember a page I was in
before closing a PDF document and would restore it when opened after.
So I took MuPDF v0.9 and implemented it. You can find my fork here:
https://github.com/Asido/MuPDF
I assume it wouldn't go easily into current version since v0.9 is half
a year old. But if you like it I could take care of that. I made it
for my personal use, so I didn't took windows nor iPhone into account,
but again, if you like it I'll take care of that too.

The way it recognizes the files is by generating a sha1 hash of first
64kb of the file. History is stored in mupdf.mark file in XDG base dir
(~/.config)
Since I read a lot of big PDF books, which take weeks to go through,
this is extremely helpful feature to have. It could also be extended
to allow manually insert bookmarks into different pages specifically
for each book and having a small simple menu to go through them.

So let me know!
