Hi there! Just wanted to share with you a new way of using Quick View that I discovered recently. In Snow Leopard, you can hit space button not only in Finder window, but also when in “Open” window of OSX applications. You can equally use this functionality while attaching a file in a web based service like Gmail. Click attach, find your file, hit the space bar and preview your file before attaching…

Good tip. I use this from time-to-time myself, but I don't think long-time Mac users realize that this is there.
I use the quick view everyday. Scrolling works while in quick view.
