Auto-lock/sleep timer?

Hi! I've woken up some mornings with my iPad still on with a comic page up, and the battery was at 15%. It appears YACReader disables the iPad's ability to auto-lock/sleep. iPad auto-lock timers can be pretty long (up to 15 minutes), so I was wondering if there is a method to allow auto-sleep, or if an option can be implemented in a future release? iPads can take a long time to charge back up, it would be nice to avoid the risk of that being necessary when reading in bed.

Thank you!

While reading open the options view, then settings (bottom right corner button), uncheck “Prevent device from sleep while reading”

Ooh there it is, perfect! Didn’t notice that lower right option. Thank you!
