This happens on every view of the calendar but is most noticeable when in the agenda view.
When editing an appointment from the agenda view, you select an appointment an open the details (fully opening the appointment not preview). If you then close the appointment using the collapse button in the top right, the view resets to the top of the page again. If I am adding or editing multiple appointments 6 months from now, every time I open an event, I have to scroll back down. It would be better to have it save the spot you are currently at.
