If possible, please extend the amount of time that the site will stay “logged in” before requiring the teacher to log in again. With the current features, it is impossible to “set up” a day’s worth of activities and keep those pages open until needed for classes. As it is now,, I have to log-in and re-open each and every activity/video that I want to use during each individual class. This takes time, is cumbersome, and can mess up the flow of the class.
