I don't know how easy it is (or if it's even possible) but it would be really useful to detect what add-ons are enabled. Things like Adblock, Flashblock, cause a lot of trouble and some users don't even know that they have them installed.
I also wonder whether it's possible to detect whether Flash is actually enabled. I disable the Flash plugin on Chrome by default, but tools like this generally don't pick up on that.
