Great tool - Thank you!.
It would be nice if the diagram, after it renders would scroll to either where it as last scrolled or to the point where the cursor is resting in the text panel. This would remove the need to scroll after every time the diagram renders when adding or editing lines. This is particularly true of long diagrams where a lot of the graphic is out of sight.
Also it would be creat if, when you clicked on an element int he diagram that the text cursor would jump to that point in the text.
Thanks,
Pat.
