Because of the new BorderPane layout, the size priority is given to the Canvas at the center - except the Canvas can't be resized, so blank spaces appear at the borders. Meanwhile, the right-hand side doesn't change size, while the pane attached to that would be much better suited to handling the resizing.
This could be easily fixed by changing the Canvas to be in the left area of the BorderPane and moving the ScrollPane with the Console in it to the center area. But that is counter-intuitive to the way I'd like the screen to be designed, so it would be nice to find a different way of fixing that.
