I’m adapting a book, and I’d like to make a couple of the Appendices into chapters in the main text. But since they are part of the back matter I can’t drag them or save them to a different part. Is there a way to do this, or do I have to create a new chapter and copy all the material into it?
Unfortunately you cannot currently change back matter types into chapters or front matter, or vice versa. Creating a new chapter and copying it is your best option.
