New Stairs

Since wool stairs were added (giving us colored stairs that are great for decoration, placing furniture, and extending carpet patterns) why not do the same with concrete? Allowing concrete to be crafted into stairs and slabs would give us more colored options and make concrete buildings look much better. They could apply this to terracotta as well, providing even more color variety. And while we´re on the subject of colored stairs and slabs, why not add colored walls too? That would offer even more options for better decoration. These are simple things we really need.
