So I know that 1.10 is currently being worked on and Mineshopper is having a difficult time with the port because of the new rendering system but I have a suggestion that would put this mod over the top and maybe could be implemented once the port is finally done. So in this game Empyrion Galactic survival, it is a voxel based game. Think of it as Minecraft meets Space Engineers. And basically what you do is take a block, right click and this pops up Endless possibilities for building blocks.
To rotate all the shapes , there are a couple ways to do it. You can either keep the method you currently use or like EGS does is you have a keybind that switches the axis andanother keybind which rotates it or better yet modifier key+ scroll wheel to cycle through different orientations of said block.
