I use sketch up for theatrical stage design and use the SU Scenes feature to create different scenes in a play. This is made easy by the way that the visibility of tags is saved with the SU Scene.
However, it would be really nice if the settings of dynamic components could also be saved in a SU Scene. That way, a component (a piece of set or prop) which is placed in different places on the stage for each scene could have its x y positions set dynamically rather than have multiple instances of the same component which are turned on or off with tags.
