Mac OS X Leopard only: One of the nice things about Stacks—or annoying things, depending on how you look at it—is that the topmost document icon appears on your Dock, instead of an indicator of which folder contains it. To solve this problem, the icon designer at Optica Optima’s offering a set of icons for download that add a drawer-like image to your Stacks. The screenshot above displays the Downloads, Applications, and Documents folders as Stacks sporting the drawer icons. Pretty! To add the icons to your Stacks, just download and unzip the package, and move the appropriate icon to the folder. For more fun along the same lines, here’s how to add custom icons for your Mac hard drives.
