I know this post is kinda old (a month).
I just want to say that I would love this so much, I can’t even express to you how much I would love this. I actually found this post by searching for it on google, to see if anyone had yet thought of this.
The idea of being able to turn it on or off for if people wanted it or not is genius IMHO.
So in short, I like this idea, ALOT. ^.^
