I'm thinking whether there is another approach. I mean do it without
modifying org-mode codes.

I don't know whether someone here is using emacs desktop or session
with org-mode files. They restore a lot of things when you restart
emacs. Does these kind of tools work for my purpose?

If the information needed to restore the file view can be saved to disk,
and then reload when emacs starts, I get back the old view. I don't
know how org-mode works, if it is using mostly emacs data structures,
there is a possibility that they can be easily saved and reload. Just
like how savehist and saveplace works.

I might be wrong because I really don't know that the details about
emacs lisp. Any suggestions or comments?

This is part of what I'm looking for. Thanks for bring it up.
