Reorder all-day events / Calendars

I've noticed that all-day events are sorted by the calendar they belong to (calendars related to an account, such as google), while events within a calendar are sorted by reverse alphabetical order.

I think that there needs to be at least an option to reorder the calendars (they currently have no order), so that events are ordered accordingly. It can be easily done by a drag-and-drop in the calendar menu or in Preferences -> Calendars -> account.

Possibly, an option to change the order of events within a calendar could also be added (at least correct alphabetical order, or maybe manual order).
