We have focused on text quality and viewing options, including increasing and optimizing the default zoom level for the user when entering the book, while adding easy controls to increase or decrease zoom levels, fit-to-width or fit-to-page. In addition, you can dismiss the side panel to increase the viewing pane for the book.
We also added a continuous scroll. And we retained page-by-page navigation but improved its placement so that no matter where you are on the page, the controls are readily accessible. Go to page continues to be an option as well.
