Especially incoming profiles can contain lot of filters, services and exceptions.
In small environments the workbench is useful.
But in larger environments - more than 25, 30 and more rectangles - this workbench is not useful. You have to slide in/out parts of header or left side, you have to decrease size until you cannot read the letters. I am not really happy with this tool. And as mentioned in other posts - nothing you can use for documentation.
