Great job, thanks
The only thing I'm missing is the posibility to define an an area with contents that do not rescale.
Let's say I design a VBox with two fields. One of the fields contain another VBox with table rows in each field. This VBox could contain up to a hundred rows so I want them to have a minimum size and a scroll slider to be added automatically if the total size of the second VBox becomes too large for the first VBox. I guess the MinimumSize property should fix this but it does not seem to work (or perhaps I am using it the wrong way)
