Offer a delay before shutting down

Here's a suggestion I made time ago.

Intrepid sports a new close menu. It would be cool to have an option on it, to delay the chosen option. This would allow the user to watch a movie in bed, for example, without fear of falling asleep and leaving his PC on during all night.

This already exists as a modifier for the "shutdown" command; this would just make it more accessible to the casual user.



Also, it would be cool to have a notification when the system is about to close.
