DragThing is a desktop launcher utility that can launch applications, open documents and folders, store text and picture clippings, and do many other customizable actions with a single click or keystroke.
DragThing also allows you to define a wide variety of hot keys. These hot keys can open items in docks, control various other aspects of DragThing and even control the visibility of and switching between other applications running on your Mac.
DragThing can also provide you with a Trash on your desktop, play sounds in response to actions like ejecting a CD, and a lot more besides.
DragThing is shareware. That means that you can download a copy freely to see if you like it, and if you decide to use it you should pay for your copy. In return for paying you will receive a serial number which will disable the reminder message at startup, and enable some extra features including floating dock windows and hot keys to open dock items.
