Krates with shulker upgrades are hard to keep track of in your inventory.

Two suggestions:

• When Krates are names and placed down it keeps the name, changing the name disaplayed on the label at the top and dropping a named Krate when broken.
• Color in some way:
  • Dye the Shulker upgrade
  • Dye the Krate itself, by crafting or right click with a dye.
  • Dye upgrade that can be configured to one of 16 colors.
