Each customizable item has own independent list of preferences which
allows to define such options as:

*  Load Operation (whether to load the Payload arcs);
*  Edit Target (whether to edit the Root layer or the Session Layer);
*  Create a new Session Layer or not;
*  Set the default UpAxis to a new stage;
*  Set the default framerate (FPS) to a new stage;
*  Default measure discreetness metadata (e.g use meters/centimeter);
*  Default FrameRange of the new stage;
*  Create and Set defaultPrim to a new stage.

For instance, the new stage options window allows to define such preferences as 
up axis, measure discreetness, default FPS, frame range, target layer etc.
