In fact, all archetype compositional structuring is done with "Slots" (via the use_archetype keyword). The question is just how to clearly represent the slot idea on the screen. The Ocean editor uses some funny shapes a bit like the idea of keys (i.e. then you indicate what things can fit in the slot), but I am sure the graphics wizzkids from Link?ping will leave our efforts in the dust;-)
