Mac: Dragging and dropping folders and files is one of the easiest ways to move things around on a Mac, but the problem with it is that you have to have a destination folder ready. DragonDrop is a simple app that adds a holding bin to store data so you can find the destination folder easier.
To enable DragonDrop you simply shake your mouse cursor around and you can dump whatever file you're holding into DragonDrop. This leaves your mouse free to hunt down the proper folder or program quickly. The handy thing about DragonDrop is that it also works with folders, text snippets, web sites, and even colors. DragonDrop is $4.99 in the Mac App Store or you can get a free trial from the developers website.
