Requesting again, as the previous request by someone else didn’t go anywhere.
If you want more depth and innovation with item-based game/islands. Adding RemoveItemIndex() to item_remover_device would be a significant step towards enabling more complex and engaging inventory management.
Along with that, ItemRemovedEvent() would also be a step toward enabling more complexity. If I were greedy, I’d ask for a hasItemIndex() method. It could replace a massive number of conditional buttons.
