DragThing [OS X]

Problem: There's a need for folders to drag files into, to clear them off the desktop.

1) Make folders in ~/Documents.

a) Could make aliases to these folders (so that they don't disappear if deleted by accident) on the desktop, but folder icons get mixed up with other files and it's hard to keep them in the same place all the time.

b) Could put folders in the Dock, but they jump around when you try and drag files into them.

Solution: DragThing, an immensely customisable, unintrusive shareware app that provides (among other things) a dock-like window that holds folders and hides off the bottom side of the screen when not in use.
