Configurable: ( how do I configure? )
mustSneakToPickUp (default = true): When enabled, will only pick up the minecart when the player is crouching and holding right-click.
To pick up: Hold right-click and crouch while looking at the minecart. You can release the mouse button while moving the minecart.
To release: Right-click the minecart again.
Here you can see a minecart being picked up; be careful with a tnt cart!
