If you start director, it loads the last state of the console, this includes the settings, the configuration, the libraries, and all scenes.
But it does not recall a show or a scene by default.
For permanent use, you need to save a show.
This writes a copy of the actual state to the memory.
Renaming doesn’t affect the content of the actual show.
It just renames what was stored.
If you change a parameter, the last saved or recalled show has not the same content as the actual state any more and when you recall a show, the actual state of the console gets overridden with the content of the show, and the state before the recall is lost.
The same applies to a system without a surface.
