I think, it will be helpful to show the story like an attribute (in the objects or walls settings), when an element will be placed in 3d view.
At the moment this will make it easier to work more in the 3d view (not essential), but in future versions it will be possible to add and edit freeformed elements, which can't be defined totally in 2d views.
a furter aspect is the possibility to see directly in the attributes of a element, if it is placed on the story (or above or under)
best regards
