Yes, you can customize the Front Matter pages in Atticus. Atticus auto-generates the Title Page using information from your book details. It also provides a Copyright Page template, which you can customize, and a Table of Contents that updates as you edit your book.
If you prefer, you can delete and create your own Title Page, edit the Copyright Page, and choose different templates. However, the Table of Contents is essential and cannot be deleted.
You can also add additional Front Matter pages in Atticus by clicking the three dots beside the 'Add Chapter' button. Atticus provides presets with special formatting for these pages that you can further customize using chapter formatting settings.
