Ratings and reviews

This is a dynamite epub reader - the best I've used, and trust me - I've tried them all. I have a number of authors who write a series of books, and they're best read in the order they've been written (new situations, new characters, etc). Michael Connelly, David Rosenfelt, and Tana French are just a few such authors. What I do it edit the filename to tell me the order: "1-Book 1 to read," "2-Books 2 to read" etc. That works great - as long as the epub app lets me select books using the file system. But most apps don't do that - they have this fancy 'library' system that shows you the cover, and defaults to the embedded filename. Then I have no idea what the correct read order is. Not good. Secondly, I really like being able to adjust the look of the book - font, font size and color, page color, night mode colors (just a choice of black-white doesn't do it for me). Cool Reader has every adjustment I can think of. And, the final readable page looks so much better than any other reader I've tried! So if either of these situations involved you - consider this app. I don't think you'll be unhappy. I see where someone complains that they want to read PDFs and this app doesn't allow that. But there are many online and free converters to convert any PDF into an epub - or, use Calibre which is totally free.

Is there a way to lock the settings when you change them? Nearly every time I turn the page while using this app, the settings accidentally change, ie. the margins change, the font changes, the line spacing changes, etc., and it's very aggravating. How can I lock in the settings once I'm changed them to what I want?

Why not external SD card access? I think it's a bit better than older one just same problem with sd cards here on android 7... Hope for the proper fix sooner. And if it's possible the book cover to be changed to optional.
