Add a sleep timer to stop reading
Many readers enjoy reading a book before they go to sleep. Having a configurable sleep timer would let users read until they fall asleep without losing their place in their book. Ideally, the app should make a bookmark of some kind when the book stops reading so the user can pick up where they left off the next time they open the book.
Most schools like to track student reading time. It would be wonderful if there was an option for students to keep track of how much time they spend reading. In addition, many teachers and parents will tell a child "read for x minutes" and having a timer would help them stay on track instead of repeatedly asking "how much longer".
Having the ability to have a timer setting for when I fall asleep listening to books would be great!
I believe that you can do this by going to the clock app the setting a timer and changing the sound to "stop playing."
Go to the clock function, timer, and select sleep iPod in the When Timer Ends.
