The 2D Node toolbar

Using the 2D Node toolbar it is possible to edit specific nodes without XL or RGG. If you select a node the toolbar (right above the 2d graph view) will show the possible options. Please select the A node and press the appearing "addNodeSuccessor" button in the 2D toolbar to add a child of the type of successor to the node A. The then opening pop-up window can be used to describe the type of node you wish to add, for our case the suggested F is completely fine.
