@kiwidude: Would you be willing to update
@user_none's APNX generator plugin and add option to use page number value from custom column (Pages)? Just as Calibre can use that value instead it's built-in algorithm, when sending mobi/KF8 books via "Send to Device" function.
Or merge the two plugins / add APNX generating function to this plugin (Count Pages)?
It would be very useful for people who read on Kindle device and Kindle for Android (for which "Save to disk" must be used for sending books, and standalone APNX generator plugin after that). Currently page count for the same book differs significantly between the two, and it kind of defeats the purpose of having page numbers
