The correct implementation of Bundles

According to Mojang, the primary reason bundles were delayed is due to UI difficulty on mobile devices. A simple solution to this would be to make the bundle an equipable item, like a backpack or satchel.

• When equipped, it would simply add an additional row of highlighted inventory slots to your inventory. (kinda like this idea, but with only one row of additional inventory)
• When you remove the satchel, all items in those slots would be removed with it, allowing you to give the satchel to another player, store it in a chest, etc.
• You can name and recolor satchels, of course.
• On PC, you may be able to hover over it to take out items quickly, as well as being able to right-click to pick up. On mobile, tapping on an item and then tapping on the satchel will transfer the selected items to the satchel without needing to equip it.
