A tool like the Sermon Editor but for Sunday School. At one time another Bible Package had a tool that you picked your scripture or your study, then in prompted you through discussions and then suggested questions for each section. It allowed to set the study to 30 mins, 45 mins or 60 mins. Also allowed you to selected age of target group

Reading plan would be great on the books also (not just Bible). We are starting a Book Club at our church on "Experiencing God". I will have to manually create the reading plan unless I have missed something.
