reading while listening
I am surprised that this question hasn't been asked already.
Since audiobooks moved to the ibooks app, it has become impossible, as far as i know, to listen to an audiobook while reading, because you can't set the audio to play in the background and go back to the library and select a book.
You can however move the audiobook back to the music app, but that's not ideal.
Maybe there is a way, other than waiting for an update?
