(It would be helpful if you would quote what you're responding to, so people can see the context.) I *think* you are claiming that the 'concealed' feature is simple and easy to implement. In fact, the existing visibility rules are already quite hard to implement. (I've done it; either I'm stupid, or it's hard to get right. ;-) ) I suspect 'concealed' would add a fairly large hunk of complexity. Not impossible, but probably not worth it. - Bob
