The change log for appointments, especially when appointments are postponed, should be urgently optimized. Currently, the log can only be viewed for the appointment on the respective day. However, as soon as an appointment is postponed, important details are lost — for example, the original creation time of the appointment, as it was assigned to another day. A solution would be desirable in which the **complete record of an appointment is displayed at any time — regardless of whether and how often the appointment was postponed. In this way, the entire history remains transparent and comprehensible.
