Denied "I'm Away" Doesn't Actually Do Anything

The away option when you edit your profile doesn't seem to do anything as far as it seems.

I think it should at least display on your profile that you're away, and change your green square orange or something, and when you hover over it, it shows the reason and return date.

I think this would come in handy for group owners, and members in general. It would be nice to subtly tell others that you're going to be away for however long.
