Delete at least the empty things without confirmation

In The Humane Interface, Raskin explains that confirmations do not help prevent destructive actions, as people quickly form a habit of responding “Yes” to every “Are you sure?”. To protect the user’s data from their own mistakes, it is much more effective to implement the undo feature ubiquitously.

But if you are too lazy for that, at least check if the thing I am deleting is valuable. Adobe Lightroom is at least this smart: when you ask it to delete an empty folder, it does so stat. Apple’s Reminders, on the other hand, is very dumb: when you try to delete an empty list, it still wants to make sure you are sure.
