Just suggesting a filter option under library and updates to show only unread chapters in case I skipped some titles but can't remember what I skipped over.
I would love this, similar to Gmail filtering unread emails or manganelo that lets you see in notification all the newest chapters that came out for the mangas you follow and filters which chapters you haven't read.
I believe something similar has already been suggested here, so you may want to go give that thread a bump. I've also been thinking of suggesting this feature for a while, so I'm glad I'm not the only one who's thought of it.
