Describe my idea? Aight mate

Within the placeholder you just specify the key of the item and it returns the amount of the item the player has.

If the player has none of an item it will return 0 and if a player were to have a stack and a half of something then it would return 96

This one is actually already in an unreleased Spiffy build, but I think I will remove it from there and port all placeholders I added there to FM. I will close this as duplicate because it kinda is, but yeah, it will get added in a future FM update 😅
