Kramer Control Reference spaces
Reference spaces are useful when you have multiple identical spaces installed within the same site.
The reference space option allows the programmer to create additional duplicate spaces without having to open the Builder and recreate the GUI.
Another benefit of reference spaces is the ability to publish changes to all references at the same time.
You can make changes to the Master space without affecting the references, and once you have the Master space updated and working as desired, you can publish all references to push the latest changes that are appearing in your Master.
