When your in a survival world and you've accomplished nearly everything you can do, you would probably stop playing it. But what if I told you there was still something you could do? All you need to do is download the link right here and put it in your specified world's structures folder!

With this all new custom command creation, four new blocks will be added to your world, all only obtainable through Floor Crafting. Those are the Block of Creation, obtainable with a block of Mycelium and a rabbit's foot, the Block of Sin, obtainable with a blaze rod and a nether star, the Block of Bravery, obtainable with a dragon egg and an elytra, and finally the main purpose of this command, the Creative block, obtainable with all of the other new blocks added. To switch to creative mode, just drop the item on the ground, then you will get another block called Survival. Drop that block to switch back to survival.

-[WARNING]-
If you die in a singleplayer server with the block, the block will disappear forever. If you die in a multiplayer server, the closest other player to the block will get the block and turn into creative mode. Be careful with this.

This custom command allows one more extension to your minecraft survival world. It will be long and painful, but it will be worth it.
