Add option to expand inventory space in creative mode

When working with complex redstone or making large builds with many components, it's often very frustrating managing your inventory. Please add an option in the settings to increase the amount of inventory slots in creative mode. Even with GUI settings at the max (Scale 4) there is loads of room to expand the inventory in all directions.
I think this is a good idea, because I don't see any downsides. Since it would be entirely optional, those who find it overwhelming or don't like it can simply ignore it, while those who choose to use it would benefit greatly.
