It could be nice to suppress (hide) operations and properties according to their visibility
In order to format a class according to the context it will be used.
For instance, if I need to show how to extend a class, I would like to show also protected methods in my diagram. By other hand, if I need to reference the same class in a diagram that use it just by its public interface I don't like to show protected methods.
