Minecart Upgrades

Minecarts are cool, but what if there were more use to them?

Like being able to chain minecarts! What I mean is, in a crafting table, using a regular minecart and a chain, you get a "chained minecart" which if you right click a regular minecart, it connects to the regualr one. meaning you can bring (a limit of 5) friends in a minecart ride. You literally could make a train if you have a texture pack.

However, it wouldn't be a train without fuel. That's where the next idea comes in! With the crafting table we used earlier, we can use the minecart crafting recipe but instead with iron nuggets. Using the ingredients we can make a new item called a "fuel storage". You can right click a regular minecart (not a chained one) with the fuel storage in hand to place it on the bottom left/right of a minecart. From there you can add any fuel source to make it go faster. For example, using coal will make the minecart 2x faster. While lava makes it 9x faster. (P.S. You cannot combine fuel storage like now coal and sticks at the same time, otherwise it would just be to OP).

That's all I have for now. Let me know what I should add next.
