I had an extension called, "turn on tag in all scenes" enabled in sketchup.
It would ask me if I wanted to have a tag to be visible or invisible in all scenes. It was not working properly so I deleted it. But now I cannot find the extension. It is great. It allows you to make a layer visible or invisible in all of your scenes.
I know about the extension "auto invisible layer" it allows you to create a new layer and it doesn't turn on in all of your existing layers.
Have you heard of this extension? Where I can find it again?
