Delving into the text-to-speech (TTS) feature: (1) There is zero documentation anywhere, which makes it annoying. (2) When you figure out how to access it, you find it uses Microsoft Bing's voices, and ONLY those voices specific to your geographic location, making it annoying. (I personally prefer British voices, but you can't get there from the USA). (3) OTG it has useful reading speed controls, unlike the hobbled nonsense Apple imposed on its TTS reading controls. (Thanks Craig not). I definitely prefer Readest over Yomu, despite Readest's nearly worthless documentation for anything. Let's hope Readest keeps growing up.
