Re: Sharing "Next" feature problem and Importing Links reversible links
It does not matter in which order it downloads, you have a Sort button on top of the reading list screen, so sort it in the correct order. Either sort by name, if names are consistent, like "Chapter 139 - blah blah", or if not, sort in reverse order by file date/time, if they really are downloaded in reverse order.
Or sort manually with the hand icon at right of each item. I will not "fix" in any way the follow next function, it's not designed for this purpose.
