Mountain Lion contains two new apps for your Mac (which I am finding that I’m using more and more): The Reminder app., and the Notes app. I don’t think I have to tell you what you use them for.
But did you know, that one can take a note or a reminder, and “Pin It” to the desktop.
1. Open either application.
2. At the top of the app, double click it.
3. Boom! The current note or reminder is now “pinned” to your desktop.
