@LillyStoryTeller As a new reader, (as in, I'm a fetus to this fandom, as in, I just started reading today) I feel like the older chapters do add a bit of clutter but I can understand why you'd want to keep them.
I feel like moving them to their own book would be better than scrapping them altogether (or rather, moving the revamped chapters to a new book), though I know that can take a lot of time. I don't know though! Lmao, I just thought I'd add a suggestion I'm sure you've already thought of!
