@that_one-person I saw some advice that was really helpful for me about extra chapters, maybe it'll help you! If you feel like its completely irrelevant to the readers who are reading now and of no importance, then go ahead and delete it! But if it is something like a tag, bonus chapters, or important information about the story then give it a helpful title name that lets the readers know and move it all to the end of the book for people to look at if they want to!
