Perhaps the right approach would be to still use constraints to describe the layout, but to infer those constraints from examples provided interactively by the designer. The workflow would be: 10 designer creates an initial mock-up 20 designer re-sizes the window / uses another device 30 designer alters the style on that new format, re-sizing boxes, changing font sizes, etc. 40 constraint solver finds a minimal set of constraints consistent with the designer wishes 50 goto 20
