What made me do the two options thing is that I was thinking the one was for a developer to say when it could be used, and the other to hide it.  What I actually wanted is to have it default hidden and have my module use case turn it on.  That doesn't allow the wagneer to hide in in that case, but thinking about it, that is what I wanted, or at least I can work with that.

Does this look right for how to add the show in a module view:
 #{ _render_header args.merge :hide_menu=>true, :show=>"type #{args[:show]}" }
If I don't have the #{args[:show]}, then other show options wouldn't get to lower level view, right?
