SO MANY IDEAS!!!!!!!!!!!!!!!!!!
furnature, shap-shifting mobs, less computor reqirments (im running windows xp of a dell dimension 8200 so its really laggy ), a bult in mod maker (every time i want a mod its outdated or needs a differint modloader), lots of dimesions ( one of them should look simalar to the aether ), instant server with worlds that you can choose the design of and need portals that are costomisable such as the overworld needs dirt in the shape of a nether portal with a peice of stone to start it, more mobs( fish peguins ext.), better moving (sliding climing backflips ext.), motorcycles, a built-in modloader, teleporters, more weapons, slenderman, more tools and taimable dragons that lay eggs(you have to get the enderdragon egg and put it in a crafting table with fish and dye.
