If you'd like to exit the editor, you have two options:

• If you have made changes you'd like to save when you exit the Travel Book Editor, press the 'Save & Preview' button. You will leave the editor, and your Travel Book will be generated, including the changes you just made. 
• If you have not made any edits or if you don't want to save your changes, simply press the cross in the top corner, confirm your choice, and you will return to the preview.
