Mac 101: Drag and drop in the Application Switcher

We've talked previously about the wonders of the Application Switcher, the translucent bar that comes up when you hit ???-Tab. However, thanks to Macworld I realized today that the Leopard version adds a great feature that should have been there a long time ago: drag and drop. In Leopard the application icons in the Application Switcher are live. This means you can grab a file in the Finder, hit ???-Tab, and drop the file on the running application of your choice. So, for instance, you can easily drop a plist on a text editor instead of using the default plist editor. In previous versions of OS X you needed LiteSwitch X ($14.95) to achieve the same thing (though it's true that LiteSwitch X still has a few tricks up its sleeve that the default Application Switcher is missing).
