ImprovedPropsA prop is used in the scenes you tick. The card's Used in scenes lists every scene of the production, the item's own pressed and each one saying what that scene does to it; press another and the item is used there too — its description, quantity, grade, handling, source and notes copied as the card has them — so the scene's own card shows it without anything being created again. What a scene decides stays that scene's own: its state, its approval of the description, its plate and photos. The scene you are on stays pressed — Delete takes the item out of it — and taking it out of another scene asks first, since that scene's card goes with it.
