Better MInecraft

I was wondering what you guys thought would make Minecraft better. Personally, there are two things I want, beta world generation back and vertical redstone. The world generation for obvious reasons, the new generation is sooooo boring. The vertical redstone so as not to take up a ridiculous amount of redstone torches and also to make a Mario themed adventure map. If I could place pressure plate on the bottom of a command block and jump to hit it, I would be able to make a really cool map, but I don't think that will happen anytime soon. But I would like to know what other people want in Minecraft, so tell me. Please and thank you, Me.
