Preview lets you take a look at what your simplebooklet will look like in desktop view for your customers. It's a good way to get a sense of how all of the features and interactive elements you've added to your simplebooklet will work. You'll also be able to experience any of the custom design features you applied from the Presentation tab.
To access the preview, tap the PREVIEW tab in your toolbar.
You can experience the booklet just as your customer will.
Click the back button in the top left corner to select which toolset in the simplebooklet designer you want to return to.
If everything looks good, publish your simplebooklet from the PROMOTE tab.
