Feature request: Word Overcount

Hi,

As a journalist and copy-writer, I’m often called upon to deliver a set length of copy, no less and certainly no more. The way I research and write means I tend to start out with a lot more than I need, and whittle it down to the required length. It would be great if Scrivener had a counter that showed how far over your target word count you were.

Thanks,
Bash
