about the last page thing, it only works on horizontal reader, and yes, I'm thinking some way do download the mangas as a zip file, but there's some problems with downloading files on android
Oh. so that's why it didn't work, I've only been using the vertical page scroll on all the manga that I've read. Good luck on tackling the download problem as the nhentai and quite other require a torrent app to fully download and view the page of the manga
