One of the main things I have always wanted to be introduced to minecraft is Levelling. When I say levelling i mean: Maybe when you destroy or put down a block you get a certain amount of xp. The second thing I have always wanted is for there to be a Campaign or something. I think it should be set like the yogs cast, where you go on an adventure through a pre-made map and find clues and stuff. There was also one other idea that I thought was appropriate to include and that is to Add friends. There should be like a tab or something under multiplayer that says friends. When you go in, it should tell you if they are online or not and there should be like a send message button or something. (also a join game button :D)
These are my three main ideas that I want to be brought to minecraft.
Thanks
