Whenever I'm making a terrain build, sometimes I realize that I either made too small of cubes where I could have placed a bigger cube in general or I placed a big cube right where I was going to make a cave. Then comes the idea of this.
Cube breaker:
The cube breaker breaks down cubes into smaller cubes.(e.g. 64x cube breaks into 8 32x cubes and 8x cubes break into 8 4x cubes)
Cube repairer:
If you accidentally broke the cubes down too much, you use the cube repairer to automatically find 8 cubes formed in a square, and turn it into a bigger cube.
With these tools, you won't have to re-build the stuff that's on top of the cubes in order to replace them.
