Woah guys, seriously, calm down! If this is a joke, I hate you. If this is intentional.. I will drag you jerks to the depths of hell~
slabs & stairs of every type (except maybe the odd ones, like TNT or hay) sideways slabs & sideways stairs
id actually like to see wind effects and better shadows (that doesnt aquire great pc abelities) like ik theres shaders, but they could do storms so it would be harder to move in a storm or just organic things will move with the wind. id also wish they would add so you could mix 2 slabs together (examble stone and wood) and add log textured fences and "walls"(like the stonewalls) and bring back metadata. and it would be cool with vertical slabs. slab glass. birds, or just nature sounds in general grass slab bushes (a plant that is like the double plants(peony and roses) mountain chain biome, like real mountains and not extreme hill mountains sharks fish turtles more neutral mobs in general add iceicles that would work as cobweb add chains and rope, and hook's let leather hang on a hook add more plants as i said befopore, bushes, and cherry trees, berry bushes add a randomizer for redstone, which sends a signal to a random side of the block add achievements with rewards as in items or xp add custom bed so you can have a bed without anything on it or with madress, pillow and blanket, and like banners, without madress, pillow and blanket you wouldnt be able to sleep as long as with a complete bed add chairs add cabinets add shelfs add fossils (youll gain bones for digging/mining the dirt/sand/stone/sandstrone blocks) add more mobs in nether smarten the villager AI add more villager versions (example builder, miner, tree cutter, knight/guard, sales man, fisher man) add so villagers will expand their city when you trade with them, and let them upgrade their buildings, and build more stucktures corals (like flowers but under water basically) remove airpockets in stairs, slabs, signs, ladder ect, under water and lava add snowstone(stone with bits of snow on it) add icecobblestone, snow cobblestone (like mossycoblestone) add ice/snow stonebrick (like mossy stone brick) add mossy/ice/snow stonebrick/cobblestone stairs/slabs/walls add all blocks of pressure plates and buttons for traps and hidden stuff add fishing net /can be added to a boat or in the water at the shore add water monster add whales, crabs and other sea creatures add sucken ships and ruined cities under water ofc add fallen castles/forts/other buildings where mobs will spawn to protect the loot in the structure add campfire add hydration meter as another healthbar add fresh water (would be clear where the saltwater would be more green/blue depending on the biome add cold and warmth meter, you can bee too cold if you are so your hunger meter will go down faster, so use campfire to warmth, or furnace or fire add candles candles has more of a dim light than the torch but better than restone torch but is easier to make (wax from a flower which will appear almost everywhere, and string) add backpack (crafted by 2 string and 6 wool) another "page" of enventory, but at death youll drop your backpack which will stand where you died seasons (grass and leaves will turn green -> yellow -> orange -> brown -> brown/green -> repeat) (flowers will die in winter/fall and bloom in spring/summer) thats most of my wishes for the future of mc
