The ability to draw on bricks will be possible if someone makes this idea I have. My suggestion is if someone can make some chalk you can draw on any bricks you want and, if you made a mistake you can get the eraser tool. Also add some commands such as for example "/clearchalk". And a command to save and load your artwork. Even if this idea never gets made I just thought it would be cool to draw on bricks rather then print on them people hosting servers would love this for added detail to their builds.
