My minecraft idea

First of all i want to say that my english is not that good yet sorry if i type something wrong. Hi mojang i think a great idea for the chaos cubed uptade would be that a player can make the sulfur cube invisible with the block inside it visible. I know you can do it with the invisibility potion but it has a time limit. I suggest that if a player uses a phantom membrane on the sulfur cube it will stay invisible as long as the phantom membrane isnt removed. And then you can remove it if you want(i didnt think of an idea how to remove it). Thats all thanks for your time reading this message and im happy with the uptade i give it an 7/10 not the best but not the worst
