Yes

A fantastic little app. I love having a convenient and unintrusive place to drop files that I need easy access to for a short time before they move on to a permanent home. I prefer to keep a neat Desktop, and Unclutter makes this effortless. The notes panel is a perfect spot for temporary and frequently-accessed bits of text. The ability to drag out a panel as a floating window is ideal for moving files around between apps and for easy reference to text on the note pad. Finally, the activation method is very clever, since its so easy to trigger but unlikely to be tripped by accident.
