Shouldn't Quarks.gui have a SCScrollBar?
In my 1280 * 854 screen resolution, I only see half of the available quarks (I think).
I tried to add scroll:true here:
window = GUI.window.new(this.name, Rect(300, 60, 550, height), scroll: true);
but it doesn't seem to work with the FlowLayout, but I didn't have much time.
