The problem is that any value I applied could only be temporary and would not survive a calibre restart. And the set of data being marked would give you different results every time you ran the scan against a different selection as it would have no memory of books you have scanned previously. At the moment I only mark the books that were updated from your selection. I could add marking of books that were scanned but it doesn't seem very useful. I could add marking books that were not updated but as I said above that is complicated by the reasons why they weren't updated.
There seems to be several different questions related to this floating around between the various posts. As looking at what books in your library that do not have an isbn and that you haven't scanned as yet is a totally different requirement from books that you just scanned but could get no isbn from. So until I see some clarity on what it is you are trying to achieve I am not going to change the current behaviour.
My usage of extract isbn is pretty simple as I just add a bunch of books, select them and extract then run download metadata. I don't get hung up on having an exact value from the book, to me it is just a tool to increase the chances of metadata download picking the right book. So if extract isbn fails I don't care so long as title author search gives me the right metadata result. And if that fails then I use my goodread sync plugin for it's link book feature to search Goodreads website for a more useful edition, drag drop the URL back onto the linked book dialog and have that plugin configured to overwrite the isbn. So then I can just fire the metadata download again.

No. That isn't anything to do with this plugin, that is just the way the metadata download works, and it prefers 13 digit isbns.

No. Why would you want to, how are you going to tell it which books to scan?
However you could take a look at the scripts thread linked from the first post in this thread. Of course those scripts have very different internal code to what this plugin now does. I originally based the plugin on logic in one of the scripts but found a number of issues with it so since then it works very differently in it's approach to identifying isbn values in general as well as for better and faster PDF scanning.
