Hasn't Kerbpaint been neglected since, like, 0.24? I know about it, and it would be useful, but I'm going full stock. I don't mind a few more parts, and if I really needed to I could leave one face blank and call it a V-Kube. I know there are lots of mods that would make it easier, like Infernal Robotics, but my point is that when the devs at Squad thought they were making a rocket game, they were actually making a Rubik's cube simulator.
