This is one of those instruments I wish accompanied Mac OS X. Unclutter is a hierarchical instrument for OS X, which sits in your menubar. 
When you take your cursor to the menubar, it slides down to uncover three boards: clipboard, drop zone, and scratch pad. Use them like you would typically utilize a clipboard, drop zone, or a scratch pad. Unclutter just makes it advantageous. It underpins Dropbox for reinforcements and I just wish it was free.
