I built an interface to manage an audio router. A single misplaced click could take an entire radio or television station offline, an error that occured one to many times. So.. what I went with is a simple "hold-to-activate" button. If you clicked it without activation a few times, a little box would pop up and tell you what to do. Once you held the button down, it would display a counter, and once it reached zero, then it would take the action. We added a short cut where if you held control and alt it would bypass the counter entirely. At the same time it would add the previous system state to an undo list where you could revert that or any number of previous actions to return to a prior state. Once we implemented this errors fell off considerably, and errors impacting broadcast almost entirely disappeared and most of our users were very happy with the way it operated.
