Not only can you modify the fields of these nodes, but the UI elements can actually be changed via a GUI that only RALE gives. Inside the node hierarchy, the layout tab provides a GUI representation of your SceneGraph application. Select the node that you want to modify, and then select the layout tab on the right-side view. From here you can resize, move, or change your UI, whatever you want.
