Missing important features – SprintReader Review

1. Book navigation. The only way right now is the 'skip back 50 words' button. How do I open a new book and start 50% into the book? 2. Epub support. All of my ebooks are in Epub, and I assume many others use this format for their ebooks. I don't want to have to convert to txt every time I want to read one of my books. Otherwise, the app is fast and good.
