I'm surprised "Customizable UI" was so high, I'm pretty sure I was one of those who marked it down as "want least." I guess it's cool, but I prefer the browser to get out of my way instead of being something I spend time messing with.
That said, I'm happy and not particularly surprised that AI didn't show up anywhere in the top-10.
