One of my favorite programs atm - seriously if you haven"t tried it, download it- its wicked!
Y"z Dock is a program launcher like the dock in MacOS X. This application is currently in beta, so please send all reports to the author. In order to add icons, drag and drop a file (.exe, shortcut, etc.) straight from Explorer to the dock area. In order to delete an icon, drag and drop the icon out of dock. Place the PNG images for your icons in the icons folder. Right-click on the icons in the dock, choose "Property" and choose your icons images there. Right-click anywhere on your dock background and choose "Setting" to change the settings that apply to the dock itself. The clock and the trash bin are not yet implemented, but they will be shortly.
