This piece of software allows to set totally own Copperlist on Intuition screen.
Every time the screen becomes the frontmost, the Copperlist is immediately loaded.
If your screen is hidden, the Copperlist aswell. Automatically. :)
Thus this makes it OS friendly.

Note that it has no limitations of UCopLists! :)

The Test program displays simple copperlist with a static raster. 
To quit Test, switch the screens 5 times using Amiga+N/Amiga+M key combination.

Source in C/Assembler included. This package is freeware.
