I realize there is a cancellation button. It would be great if the calendar marked when there used to be an appointment there and notes when it was canceled, if it was rescheduled, etc. Right now it just shows as an empty spot on the calendar as if there wasn't an appointment there originally. You then have to track down who the appointment was originally for.

Also, it would be nice if it flagged people that canceled inside/outside of your cancellation policy. Right now someone can cancel with less than 24 hours and we wouldn't know. Thanks!
