Turn Off Confirmation Dialogue Boxes

Is there a way to turn on/off confirmation dialogue boxes? For example, "Are you sure you want to mark this task completed?"

The extra mouse clicking is tedious, time consuming and slows down the process.

I can understand wanting to have a confirmation for deleting a task, a record, a contact, etc., but not for every completion.

If this feature is not currently available, please consider adding it quickly. Very annoying!
