So im a storage density lover and I had a probably dangerous idea. Draconic Evolution Netherite Double Draconium chest.

Ive attached a image of the Single Draconium Chest

I am not going to pursue anything like that. Sophisticated stuff is really complicated as is and this would make it even worse. Like potentially in the future I could add a way to define chests made from dynamic materials with the defined number of slots, but I will see if that even happens. So I am closing this for the foreseeable future.
