Currencies
Appearance
Leaf handles player's money through "currencies". This is different to how it works in some other addons and Azalea Essentials, where you can have as many currencies as you want.
Linked/Item Currencies
Currencies can be linked to an item, where the scoreboard amount is synced to the amount of an item in a players inventory. This also detects changes in both the scoreboard and item count to make sure they are always in sync with each other.
