Concentrate Software has announced Paperclip 1.0 (US$9.95), a menu bar application that allows you to attach Stickies-style notes to your documents. These notes are document-specific so they will still be available when you switch applications. You can drag and drop images, movies, and other media to these notes in addition to having full text support. In addition, Paperclip allows you to view your notes in a note viewer.
