Upgrade: Cart Modifier

The Upgrade: Cart Modifier is a Cart Assembler Upgrade added by Steve's Carts, that allows the Cart Assembler to add and remove modules from existing carts.

Recipe
An Upgrade: Cart Modifier is crafted with 4 Iron Ingots, 2 Simple PCB, a Blank Upgrade and an Anvil.

Usage
The Upgrade: Cart Modifier allows you to modify carts, when it's attached to the Cart Assembler (place it on one of its sides). To modify a finished cart, put it in the Cart Modifier upgrade's storage. Now open up the Cart Assembler interface. Your cart and all of its modules will be shown. You can switch which modules you want to keep and remove by clicking on them. If a module is red, it will be removed once you click "Modify". You can also add more modules in empty slots.


 * New modules will take as much time as they normally would.
 * Removing a module takes time too.
 * Keeping a module doesn't take any time.

After you've "Modify"'d the cart, all removed modules can be found in the Cart Modifier upgrade's storage.
