Good idea BUT….
This app is, in a word, inconvenient. You can customize the tool bar, but you have to do so for every single new document that you open. You can highlight, but you have to select the text and then move the mouse to the toolbar and click the highlight button. Every time. At least once during every reading session this app crashed. It happens most often when after opening a document and making some changes, i try to change the toolbar. Good bye edits. Save your money and buy another app or wait for a significantly improved version of this one.
