In this module you can change the following properties of your coffee table book: 

• Format
• Paper
• Cover
• Endpaper / inside covers 
• Number of pages 
• Automated picture optimization 

In the right section you can change the properties. Changes are applied immediately and you can see the updated price at the top right. You can undo the changes, where required, with the undo function. 

If you change the format, all contents will be scaled and placed as similarly as possible to the previous design. According to the displayed information you should then review all pages once again and check and/or adjust the design where required.
