I've used beta-builds of Leopard. One of them had a very nice feature regarding stacks. If you had a folder in a folder which was placed on the dock, you got navigate into it. You opened the stack, and you could just click on a subfolder, which nicely opened up IN the stack view in stead of opening a finder window... Does anyone knows a 'hack' for this, to make it work ? This is a very nice solution, when it comes to the Application folder stack. If you move your apps in subfolders, you can just navigate in them and run the specific application without browsing in finder windows.
