One of the more interesting features in Leopard are the stacks in the Dock. For a while now I’ve been using the Drawer Icons to sit on top of the stacks to give me a quick idea of what they each are by more than just the contents. Well, I’ve just found something even better!
One of my favorite artists David Latham has created a set of Stacks in his Agua theme! They’re even easier to read and identify than the drawers! The icons are available for free via the IconFactory.
Also, if you’re not handy with the terminal but still want the icon overlays, just rename them and sort your stacks by name. For example, “Documents Stack” => “!Documents Stack”
