Void Bag/Bundle

A void bag would be akin to the ender chest. The item would function the same but it would be separate from it. 

- A void bag/bundle would be crafted with a bundle in the middle and echo shards all around it in the crafting table.

- The Void bag/bundle would work like a bundle where you can click thing in your inventory and the items would enter the void bag.

- The second feature would be to click on it in your hot bar and it would open up a UI like an ender chest and you can place items or take them out. 

I believe this would help to an extent the inventory problems while also giving bundles and echo shards more use. This allows for more explorations and gives more space in the inventory!
