[qJake]

Describe the new functionality

When certain actions are performed, first prompt for confirmation with user-customizable prompt text.

What will it look like in the Admin area?

New field(s) for enable prompt, and prompt text.

What will it look like on the dashboard?

Likely just the standard JavaScript confirmation popup since it's cross-platform compatible, or a modal, if one is easy and performant to show.
