Thank you so much for putting together this mod. Would it be at all feasible to extend it a bit further to get the classic quickbar functionality?

Think early-game, e.g. Offshore Pump. With the current mod it's convenient to quickly place it again (yay) but the filter remains even though it's likely hours before another one is needed... Ideally only manually set quickbar filters would persist without items in the inventory.

• Keeping track of which quickbar filters were set by this mod: Presumably Easy
• Clearing those filters when zero of the item remains in the player's inventory: Trickier?
