@ichimga I was shocked too but it makes more sense now! The description block is still available, only now more powerful, for activating just click on the 
besides Description in the Relations tab of the object.
But wait, there is more! If you don’t hit the for it, you can place it wherever you want inside the object. For an example of this check out my [book template](Picture thread: Sets, Relations, Types, and Templates), the description block is actually to the side of the picture, which in this case makes more sense!
