Spotlight is great. In the coming months we'll see added functionality when developers release plug-ins. But Spotlight itself definitely has room for improvement... For one, I think it needs a preview window; when you highlight an item, there should be box on the side that gives you basic "get info" information without having to "view in the finder." It could even generate a small preview, or a tool-tip. I submitted the idea to Apple's feedback. Anyone have other ideas or observations?
