Opening the stack folder instead of the stack!
This is for Leopard only. There is a shortcut that lets you quickly open the folder where the stack folder is located in the Finder window instead of opening the stack itself. You simply have to hold down "Command" and click on the Stack. The Finder window will automatically pop up. Unfortunately, it doesn't look like there is a one-click way of opening the stack folder itself (only the folder containing the stack folder).
