Hi,
is it somehow possible to protect of unwanted accidental calendar event MOVE or DELETE by adding "Are you sure?" pop-up?
I have few companies which are heavy Calendar users, they organize events via Zimbra calendar/task/todos....but sharing calendar among dozen of editors leads to occasional random items dissapearing or being dragged to another day or hour with mouse, and editor either is not aware of doing anything, or he/she knows he/she did something, but doesn't know what.
With simple "Are you sure you want to delete calendar item?" or "Are you sure you want to move..." pop-up this problem would be solved.
