Allow the use of the region debug console found in recent viewers. This console

will be available to estate owners and managers. If the user using the console
had god privs, they can use "set console on" and "set console off" to switch on
the actual region console. This allows console access from within the viewer.
The region debug console can coexist with any other main console.
