Quick feedback from my side.

Session restoration aborts with 
        Error running timer: (wrong-type-argument listp t)

Usecase:
=======

The PDF file is actually created as below

        Scanned Book (Pre-dominantly English with some Chinese) ->
        Unpaper -> Tesseract-> Text -> Org -> HTML -> EPUB -> Kobo Reader

Since the original book has Chinese characters and lots of Footnotes,
there were a lot of errors in Tesseracted file which I had to copy-edit
and fix.

During the above process, a single Emacs frame was split in to two
windows.  One window displaying page (of PDF) and the other window
corresponding text.  During the copy-edit and proof-reading stage, there
were occasions when I found it convenient to

  (i)  C-x 2 and have the PDF page fit to window width.
  (ii) C-x 3 and have the PDF page fit to window height.

Requirements from the above case:
================================

1. Restoration of page number
2. Restoration of "Fit to Height" (H) and "Fit to Width" (W) settings.

Nitpicks
========

1. Why am I asked this question again.  This question shouldn't be asked at
   all.

    `----

2. I don't know what to make of the changing page numbers in the
   modeline when the PDF page is "loaded."  Does this "counting up to
   total number of pages" happen even if the page is loaded from cache.

Tried it out.

Same here. I am running in to a timer issue.
