Text to speech
Adding a text-to-speech program would be nice.
After I download it to my iphone home screen with Safari, I use the "Speak Screen" function (swiping two fingers down from the top of the screen, turn it on in Accessibility settings). It then reads the entire prepub to the end on my phone. Unfortunately I can't get it to start reading from partially through the prepub, it always starts from the beginning, but I'm fine with that.
