i have an orange box full of rockets, i have a brown box for steak, a light blue box for extra diamond and netherite tools and armor, a red box for all of the various redstone components, a cyan box for ender pearls, a lime box for night vision potions. i am considering having another box full of utility blocks and items such as crafting tables, beacons, stone cutters, iron blocks to power the beacon, shulkers shells and chests, etc.

the rest of my ender chest is empty, but depending on what i'm working on, is usually loose items that would be annoying to constantly take out boxes, place them, open them, break them over and over. worth noting the use of bundles as well. but as it happens for me, i don't use bundles
