It would be nice to be able to sort items in the display by how many inventory slots it's actually taking up. For example, 50 Ender Pearls would take more slots (4) than 150 Stone Blocks (3), which takes more than 1,000 Dirt in a Tech Reborn Storage Unit (1).

It would be useful to know which items I need to optimize with Storage Units, or catch mistakes where I forgot to prioritize a Storage Unit and the item is spilling into shareable slots despite exclusive slots still being open.
