Having multiple mnventories in 1 Block, Item Or Entity so you don't have cram it in GUI

After Looking at the front page after awhile i noticed the first snapshot contained some inventory improvements so i thought of my own, not to sound needy but having multiple inventories attached to one thing(Block , Item , Entity , ect.) because how hard and dumb looking it is for having a large inventory screen instead of pages of inventories so you can make any size chest of your liking, no limit on inventory amount and independent inventory sizes.
