It would be better if Follows would only show new chapters added as new if chapter number actually goes up, so we don't have whole page(s) spammed with old chapters that some group was finally allowed to upload. there's nothing wrong with new version being added, but very annoying when it's shown in Follows.
Then again, new version might have extra content or for instance uncersored version etc, so some checkbox for uploader that this is actually updated version would be good, but then as OP said, just trim updates shown in follows per Title, like if it exceeds 5 chapters, show just 2 last and 2 first of the updated and dots in betweeen, so if you want to see whole thing you just go to the title.
maybe have this kind of behavior optional if some people like to get whole mangas they've already read fill the pages and try to see if there's actually anything new in-between.
