Google just introduced
Google Desktop/
I haven't had much time to play with it yet but I'm pretty sure it is supposed to be some kind of Quicksilver/Spotlight searching utility. I personally don't use quicksilver OR spotlight, I find that both of them are considerably slower (in that I have to sift through the results) compared to if I just use the Finder to click on it...
Can anyone figure out a way to customize the color (possibly blue instead of black)?
