Option to preserve original read position

Hey there! Started using the extension a little while ago and it works beautifully so far. That said, there's a small addition I'd like to suggest.

I'm guessing the extension is already aware of the starting page of the comic being backed up since there's an option to start downloading from there. My question is, would it be possible to implement an opt-in setting to make it so that the downloader navigates back to the starting position upon completion? As is backing an item up tends to mark it as read without additional user intervention, my thinking is it'd be cleaner to leave everything as it was so that reading lists and whatnot are preserved simply by closing the tab.
