Hi Franco
I would like the very same thing too :-)
It is a pretty great tool and long needed, but as you say, it would be even more great if you could lock some of the diagram or mark the part of the diagram that you would like to clean up.
Does anyone know if this is possible or will be soon?
Best regards
Simon
