Thanks Sid Chism for emaling us about this. Y"z Dock is a program launcher like the dock in MacOS X. This application is in beta stage, please send your feedback on any bug you may find to the author.
In order to add icons, please drag and drop a file (.exe, shortcut, etc) straight from Explorer to the dock area. In order to delete an icon, please 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.
