  Graphical WYSIWYG editors programming languages are popular since they allow
to control the diagram layout to express intention via secondary notation such
as proximity and topology. However, such editors typically require users to do
manual layout. Conversely, automatic layout of diagrams typically fails to
capture intention because graphs are usually considered to not contain any
order. Model order can combine the desire for control of secondary notation
with automatic layout, without additional overhead, since the textual model
already employs secondary notation. We illustrate how model order can exert
control on the example of programming languages SCCharts and Lingua Franca. We
also propose a first guidebook how such model order configurations can be
extracted for other programming languages with a graphical notation.
