Use electronic sticky note from any application

Stickies.app in Leopard can become very handy if you know how to activate it within any application. for example, if you’re on Safari.app, just highlight any text and press Shift + Command + Y.

You can drag any image, song, application or even a movie to this Stickies.app. For me it is best to arrange it on top of the Desktop Click Windows > Collapse (or Command + M), and make it run on start up.
