Hey, I love the mod but it lacks crucial thing I'm using at my provider train stations.
Could you add inventory_type = 'with_filters_and_bar'
to the chest's prototype so we can set filters for the chest slots?
Its that feature of vanilla chests that when you middle-click (by default on Linux/Windows) occupied slot or with item in hand it locks to that item so inserters/loaders/bot stop loading that slot with any other item.
