Allow the school day to be structured
Allow setting of lesson times at the beginning of the school year so classes can be slotted into period 1, period 2 (rather than inputting the time for each lesson for each class)

If you click Go To → Classes, you can enter start and end times for each day of the week, such that you do not need to enter these for each individual lesson. Hope that helps, please let us know if you have any questions. Thanks!

I would like to structure my classes (periods) WITHOUT using times. Being a primary grade teacher, i never seem to follow the same schedule twice. I would like to order my lessons without assigning times for them. This helps when I want to see my ELA at the top of my plans and Math at the bottom of my plans. If I don't assign times, it automatically alphabetizes my list, which is not how I want it seen. I've had to get around this by labeling my classes: a ELA, b Science, c Math, and so on.
