Add "Start reading this serial from the last known page"
Yes, I know this is hard because you don't know the last known page when this is clicked for a new serial. Put a marker in in this case that starts the reader at the last known page once the serial has been successfully scanned once?
We plan to provide both both “start from the beginning” and “start from the current page”. We have a different plan to handle new unscanned serials; we hope to scan them quickly enough that nobody other than the person who adds it notices, and we plan to show that person their recently created but unmarked serials.
