Fix the menu command to build Composite from selection
The menu command to build a Composite actor from a selected set of actors has been disabled in Kepler. [But an empty Composite actor exists in the actor tree and one can build composites by dragging it to the workspace.]
The menu command to build a composite from selected actors is quite useful and should be added back into Kepler. This will require correcting the Moml generated to fit Kepler requirements.
