Ho and for witch cell is selected when you put four mouse on tthe icon of a cell it's highlighted with a lignt into the 3D world but it's not explained so it's my fault.
in the first place i wanted to add the name of the cell into it but i was not able to find an estethic way of doing it. And yhea you are right on this point it's a bit frustrating to find the good one. Thanks for the feedback it's realy constructive.
