We need to be able to rotate jump pads much more freely on foundations. I've got a rather nice building for my coal facility, and it does not line up all that well with the adjacent cliff. I would like to be able to place a jump pad so that I could just get on that cliff quickly, but right now, I just can't because the only possible angles are 0, 90, 180, 270. I understand the logic of locking the grid on foundations, which I guess is also why I build that power station on foundations in the first place, but we also need to have the option of rotating things freely for those odd cases where another angle is more desirable.
