The problem you raise is one I have been struggling with as well. See, for example, the following discussions:http://forum.flyinglogic.com/index.php?topic=384.0http://forum.flyinglogic.com/index.php?topic=359.0
Good for you to raise the point again. From what I remember, for the moment the solution rests in using groups and hoisting them. I can manage with that. But rolling up or folding entities would still be a great feature, I believe. Also having access to a large printer is worth a lot. Personally I prefer to review diagrams from paper.
