After I publish the digital magazine to PUB HTML5 Cloud, how can I change the publication settings such as HTML meta title and description?

I have created a digital flipbook by using PUB HTML5. Is there any way which allows me to preview my newly created flipbook before I publish it?

I want to add my own logo to the digital publication so as to enhance brand awareness of my corporate among our audiences. Does your software allow me to do that?

I want to present my readers with a fresh and unique experience while the book is being loaded. How can I customize the loading settings of the online flip book?

I just finished converting PDF to flipbook. Anyway, the flipbook is not that good-looking. Is there a simple and quick way for me to change the layout of digital publication?
