COPS under TOS with standard ATARI desktops:
Register COPS as application for "*.CPX" files and confirm that COPS recognizes the VA_START message. You can now assign an icon for each module in MAGXDESK.
COPS will be loaded every time the system loads, CPX modules are started (which can carry out the required initialisation routines) and terminated according to your specifications. You can start any CPX files directly from the desktop by simply double clicking on the icons.
Again, control panels can be assigned icons which allows you to start modules from the desktop.
