My final request ... would there be a way to have an option for a custom application keep backlight on time? As it is I keep it set to on because I dont want my n900 locking every 2 minutes. But I would love it to say lock after 10 or 15 minutes because that means I am probably done reading but neglected to either lock the screen manually or close fbreader. It would help preserve battery. Again thanks for the great app.
