Jens has dug into his Bag of Suggestions and added something quite exciting to Minecraft - a new type of slab. As seen above, the...whatever it's called....is yet another decoration addition. This will definatly change structures in Minecraft, as blocks are more than blocks/stairs/slabs. These also bear a resemblance to the half slabs in the popular Tekkit mod pack. As seen above it looks like some blocks will be able to be placed on top of them, torches included. Minecraft 1.4 might be bigger than 1.3!Source: @jeb_
