Auto-Save

When editing an event/lesson/reservation, sometimes when my workload is heavy, sometimes I forget to hit save because I have so many things to get done. The amount of times an auto-save feature would've saved me so much time, stress, and energy is crazy. At the very least, if I haven't clicked save, a pop-up window saying I have unsaved changes that comes up if I try to click out of the event/lesson/reservation would be a major game changer.
