Nice add-on. That's a pretty neat idea.
My only issue with adding this as a default feature is that it's not intuitive to use at all. It works well as an add-on because people read about how to use it, then install it and use it. If it's there by default with no mention then nobody really finds out about it beyond word of mouth or accidentally. I'll see if I can come up with a way to make this more obvious for users.
