I'd love to see a website -- or an application available to the Mac -- which would serve as a "task review" for your Remember the Milk list.

Essentially, it would present you each task from a list or Smart List *individually*, one per screen, with an editing interface. You'd have the option of editing its metadata, deleting it, etc.

This'd be good for clearing out the detrius or reclassifying tasks.

Thought up after looking longingly at this.
