Mojang has introduced bundles in Minecraft, which are currently being tested in snapshots. Bundles can hold up to 64 unique items in single stack sizes, providing a solution for inventory organization. They can be crafted using one leather and one string. Bundles differ from shulker boxes, which hold larger stacks of 27 unique items, making them complementary for managing inventory, especially in the early game. However, bundles have some flaws, including a confusing control change from right-click to left-click and a limitation in displaying only 12 out of 64 items in their submenu. Suggestions for improvement include resizing items to fit all 64 or adding tabs for categorization.
