It is possible to assign a size to each individual node. This can either be done by setting the size in the Node Properties, or by dragging the “size handles” on the node (displayed in Figure 1). The “size handles” appear when only a single node is selected.
When dragging one of the handles, the node will resize in all four directions. That is, the center of the node remains fixed. Note, that the size of the node cannot be below 10 or above 300 in any direction.
