@kvodan You mean when they get simply edited, not completely re-uploaded as a new separate chapter, and it doesn't bump the chapter in your Follows with a new timestamp or remove the read marker? If so, I don't think we'll be doing either, since I think it would be a bit difficult to make that strictly optional and I would assume the majority of readers wouldn't want it anyway for every little change, especially if it's just someone fixing a typo or whatnot.
@Teasday I believe this has to do with the drama recently, many series have been nuked and others are now re-uploading new version for it. If that's the case though, I don't think it's possible for such feature because there's no way to differentiate a "new" upload vs. a "re-upload"
Though it would be possible to suppress notices if say someone else uploaded the same chapter just from another scanlater this could be an optional setting by the user. However I can see possible issues with it being done this way.
