The Information Provider is an addonmodule added by Steve's Carts. In the interface one can choose what information should be shown. It will then be shown above the cart.
One can choose what information should be displayed. This can be either of the following;
Name: Will show the cart's name (when named in an anvil), or "Modular cart".
Distance: The distance between the player and the cart.
Position: The rounded position of the cart in X, Y and Z.
Fuel left: The time this cart can keep on working with the current fuel consumption and fuel amount, fuel source. This will jump when the cart switches engines and fuel.
Used storage: The amount of occupied storage slots, and a percentage of the total storage occupied. A slot is "occupied" when there's an item in it, stack size doesn't change it.
