Minecraft has been an amazing game throughout the years and the additional dimensions make it better, but those dimensions are very limited. The Nether is mainly used to get blaze rods to go to the end, which is used to kill the ender dragon and get loot from end cities, but there could be so much more. A few years ago a mod was released titled "The Aether". It was an amazing mod that added a new realm with a whole new world. It added just as many items as the overworld added, it added new and crazy things vanilla minecraft never had, and was very fun to play. My proposal is that they add a new dimension similar to the aether with a lot more to do in it. I'd like it to be similar to the overworld. Minecraft has dimensions that're its versions of hell and the void, so why not add a heaven-like world full of new crafting materials, new tools, mobs, weapons, biomes, etc. This would be an amazing addition to the game and I can almost guarantee nobody in the community would complain about this addition.
