Accessibility for the Viewer
Could you add a shortcut keys / icons for selecting the text in the viewer? Maybe, have one shortcut / icon to select all of the text in the book and another set of shortcut / icon just for selecting the text that is on the screen. This will help people with disabilities that use the text to speech feature on their machines. Sometimes a mouse and a trackpad is difficult to use. It would be great if the shortcut key is one key or two keys that is next to each other, so the person would just needed to hit in the middle of the two keys.
