Survival Structure Blocks

If you want to make a huge build, but don't have the time to plan it out, this feature would be incredibly useful. For it to work, named and saved structures would have to be shared across worlds (if you built something on one world and saved it, you could load it into a different world), which would also be incredibly useful.

It would probably be best to present this as a new kind of structure block. You would use this 'Survival Structure Block' in a creative world, save and name your structure, go onto a survival world, craft the Survival Structure Block, and place it down.

when placed, the player should be able to right-click the block, to open a UI where you type in the name, choose whether you want to load a structure or save one, and, after selecting load, it would come up with a chest-like UI, where you put in the blocks required for the saved structure that you're trying to load, and it builds it for you.

When on save mode, it could also give a list of how many of each block is required for when you load it.
