Basically what I'd like to find is an extension for Explorer (or replacement even) that gives you a search bar and allows you to type in it to narrow down what you're viewing as you type. Much like the library features in iTunes & Winamp. I know longhorn is supposed to have a similar feature, but is there anyway to make this happen in Windows? It's cumbersome to search for a file in a huge list of stuff either by scrolling and viewing or opening the search pane and then typing all that in, waiting, etc. Any suggestions? (as an aside, doesn't OSX have this feature?)
