Order in hierarchy - how?

Hello everyone, i make a game where you play as the ball and collects the cubes. cubes are on the scene much (like a wall). I want to be in the hierarchy clean, so I'll always empty object and we surely do as a parent to all cubes.earlier it worked. Cubes have a simple script to rotate but the parent does not rotate, this causing ugly deformacion. while parent rotating, cubes rotate around it.
The question is: how can I have a hierarchy clean and did not set the cubes to parent.
In different words: How can I have a clear hierarchy and did not set the dice parent.
something like folder / category similar to folders in asstets.
ps. sorry for bad English, I am Czech.

 

If you are using game objects for sorting make sure that they are at coordinate 0,0,0 and no rotation and no scaling.
Then you should not get any problem with deformation.

 

It is work good, thanks for help
