With CopyPaste multiple clipboards and multiple clip sets are accessible via menu command, keyboard (command + C and a number between 0-9) or drag and drop. The standard copy ability and the normal clipboard are still available, but now instead of just one clipboard you have a Clip Set of ten; and after that an unlimited number of sets of ten clipboards.

Cool Clipboard Feature: CopyPaste saves clipboard data through restarts.
 

User Example:
Using Multiple Palettes

When I am browsing the net, I set my clipboard to use my internet clip set. Everything I copy, images, text, email addresses, all of it goes into that set. When I am formatting emails in Entourage I use a different clip set. This keeps all my clipboard material well organized. If I need something from my internet clip set when I am in Entourage, switching clip sets is only a click away.
