Lego Part Finder

I don't know if it just me, but I find it very annoying when you can't find a piece.  You search all your boxes and you still can't find it and it takes forever!  I think it would be great if there was something that could do it for me.  Thats what the Part Finder does!  You just tell it what part, colour, and the kind of brick it is and it goes and finds it for you.  For example, "Part Finder, find a 2x2 red plate" and off it goes, searching through your boxes and viola it find it!  I think this would be very useful and save a lot of time!
