New paintbrush, concrete slabs, and mirrors!!!!

So, to start of, I believe that concrete slabs are a must have to open up more building capabilities in the future. Now I now this has been suggested before, so there isn’t that much reasoning needed. Also, mirrors would be a very interesting block. I mean, it would provide neat capabilities for decoration, and block behavior. And my last thing, paint. Yes, I think it would be awesome if we had paintbrushes that we could make out of sticks and strings that we combine with due to get a colorful brush to paint wood, some stones, and even bricks with to give creative building a whole new level with textures and more. Thx for listening to my thoughts.
