A new Update

This update idea will be about a past and future type theme here's the basic premise. Once the player beats the ender dragon and get to the end cities there will be a structure of some sort then the player get to a portal room (like the end portal) but there are two portals one leads to the past and the other leads to the future (in this I am thinking the end is a gate way through time) In the Past portal the player saw new Biomes and Mobs (mobs like hostile iron goloms or a collosel bee) In the Future portal there could be a Advanced Villager Culture and maybe New Ores (also the nether should not change) That's all I really will be happy even if you see this that's this is one of my favorite idea's this would just be a way to get new dimensions but I like it oh! and you could have a biome like vote for this
