This is a helpful utility mod to allow for skipping to the end of long editable/readable books. This is done using the UI back arrow on page 1, which wraps the page number boundaries to display the last page.
Using the back arrow on a Book and Quill: skips to the last page and appends a new one, ready to be written in — if the page is left blank it is deleted for the next time you open the book, just like default Minecraft.
Using the back arrow on a signed book: skips to the last page, but doesn't append a blank page.
Here is a video of it working: https://youtu.be/ZpbcRRAqgnY
This utility mod was made for PearlescentMoon and her Dye-Duction minigame
