This is what i think the easiest way to make an e-book with Kodular.
Make a design with just a webviewer and a sidemenulayout. Webviewer is fill parent in height and width.
Use the following blocks.
The comments tell what each block does. No need for an extension, all made with the basic components of Kodular.
In the on menu item click the webviewer home url block is loaded with the html file that matches the index number of the item clicked.
So Chapter 1 is index 1 is 1.html, Chapter 2 is index 2 is 2.html, etc etc etc.
A lot of things could be added like image in the menu items or more then one group of chapters, etc etc but that is up to you.
Have fun experimenting.
