:)

 1. Pick colors which no one is color-blind to.
 2. Your friend *saw* the border, he just didn't know what it meant. I
    am willing to bet that if it pulsed, he'd definitely see it.
 3. If you add the alert icon with the tooltip as Java did, there would
    be no confusion as to the meaning of the border. I've used this
    feature live and I can tell you it was very easy to understand.

How does requiring each app to publish a separate extension on Chrome 
Store scale any better?
