Visibility
With a plugin, the visibility of an element can be set to false, e.g.
note.visible = false ;
chord.visible = false ;
rest.visible = false ;
Above set the visibility to false, in the score and in the parts.
Would it be possible to set (via a plugin) the visibility to false in the score only, but not in the parts?
(the behavior changed somewhat with one of the last versions of MS4)
