Concrete stairs, slabs, and maybe new colours?

I don't think any of us can deny we have built a 2 story house with concrete, because I do, alot. I find it really annoying that I have to use quartz stairs, slabs, or other things that look different to what I imagined.

If Minecraft really lets us build things beyond our imaginations, This fix would make that mean more.

Another thing you could do to make concrete better, is more colours. light red would be cool, and I think others could think of quite a few more.

Like I have said, this will enhance mine, and others building greatly and would Improve Minecraft building greatly.

Thank you for considering this.
