dimensions update

this feature would only be unlocked after the ender dragon is defeated and would bring more purpose to resurrecting and killing the dragon again this would allow for post game content so basically we already have three dimensions the nether the over world and the end this feature would place the end in the center of the multiverse each time the dragon is defeated would unlock two dimension that are connected like the overworld and the nether to explain more clearly it would seem that the dimensions have a ratio value to each other that places the nether at the bottom then the overworld and finally the end at the top forming a chain this update would allow more chains to be accessed through the end dimension for example you could continue the themed dimension pattern much like the end is end game content and the nether is focused midgame and brewing you could add a new dimension that could add new features to the game such as spells and magic or new materials like ores and other resources that could be used in the smithing table to upgrade current tool sets and armor you could also have each dimension be a vibrant world of its own like the nether has become in the nether update and each dimension could be lived in with varying difficulty providing a challenge to post game players and making the game more enjoyable  after you reach endgame content so that you no longer have to worry about running out of things to do more bosses could be added to these dimensions etc..
