Cairo Dock view folder contents
Hi. I installed Cairo Dock from the Ubuntu Software Center. I noticed one of the applets that was already added to the dock was "Shortcuts". When I put my mouse over it, a box opens up that displays some folders. Can I get this to happen to any folder that I move to the dock? Say I put the "pictures" folder onto the dock, how can I set it to display the contents when I put my mouse over it?
