Except it makes no sense, but I can see you're very happy with your layers.
You can't just decide that yay fundamental tapping comes first followed by aim or vica versa, one is not a prerequesite of the other just because you put them in a neat little order. You need to be able to both press buttons and move your cursor in the first place to do anything with a stream, simply one or the other might be more challenging depending on the stream/player and that's about it. (And for most people on most streams it's often tapping, which the vote seems to indicate aswell.)
