What does Start over do?

Start over clears every choice and setting you have made on this book and builds it again from scratch. Your date range, your content selections, your cover and your titles all go back to the beginning. It asks for no confirmation and there is no undo, so use it only when you genuinely want a clean slate. To change one thing, use the date range or Edit content instead — both are reversible.

Where to find it: Bottom of the Add and select content panel.
