DESC: Does your desktop get cluttered? You’re hardly alone. So you’ll love one of the most useful features in Leopard: Stacks. A stack is a Dock item that gives you fast access to a folder of files. When you click a stack, the files within spring from the Dock in a fan or a grid, depending on the number of items (or the preference you set). Leopard starts you off with two premade stacks: one for downloads and the other for documents. The Downloads stack automatically captures files downloaded from Safari, Mail, and iChat, and the Documents stack is a great place to keep things like presentations, spreadsheets, and word processing files. You can create as many stacks as you wish simply by dragging folders to the right side of your Dock. Pretty neat.
