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?

Does everything I need. Hasn't changed in ages, which is great for an eBook reader. Very configurable, very lightweight.

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.
