Hello, actually I had the same idea. I wanted to create Nassi Schneidermann and since yEd is such a cool tool, my first thought was to check if it is possible here. I do understand the comment but isn't Nassi Schneidermann another layout for a decision tree - which would be a special type of graph?! Would be a fantastic feature: build a tree with yEd and then create Nassi Schneidermann out of it ...
Kind regards, Andreas
