I know that Furniture in Minecraft is a add-on already but what if you didn't have to go to a third party website instead it could be a block in actual Minecraft. It would make Minecraft more like real life and some of the blocks would be useful. For instance a regular Minecraft furnace is boring but it would be so cool if a furnace could look more like a oven. Or, a mail box for when your on a realm and your friend lives 1,000 blocks away you could write them letters I know their is a such thing as discord but it would make Minecraft really fun. I really love to design real houses in Minecraft in creative and it would create a world of options for me and others to design.
