Thanks :)

That looks simple enough. Do you think I should integrate 
RemoveProperty() or wait anticipating Blender will do it for me with 
unregister? Also I'm confused as to how unregister() will know which 
properties belong to a particular panel? Does this mean property 
creation will change at some point so unregister() can behave this way? 
Sorry for all the questions :-/

Thanks again,
