OK so i have a few ideas of xbox only features. (Thanks to FCDarkHorse for the first 2 ideas!)
1) colored/tinted glass
3)Electric Fences! Crafted like iron bars, but with 4 blaze rods (on the sides) and 2 redstone (in the middle).
needs redstone to be powered, and transfers current 8 blocks to other fences (kinda like powered rails), and also connects to other electric fennces/oion bars. Has the same texture as iron bars, but is the color of blaze rods. Sets things on fire on contact. Each time crafted, gives 4 electric fences so its not overpowered.
4)Minecart with dispencer.
5) Ice damage (from any ice-based mobs like snow golems), and potions of ice-resistance.
