This may sound strange but I'd like for the ability to put a Mana Spreader on the side of the Spreader Turntable so I can have 360 degrees of rotation on the Y axis. I'd also like the ability to stack multiple Mana Spreaders on top of the Spreader Turntable so I can have, say, 7-8 blocks worth of Mana Spreaders firing in a line around whatever axis they're on.

For reference, I'm envisioning a more efficient (in terms of resources) tree farm with Mana Spreaders in the center and trees planted all around in a circle. I think it might push people over the edge to start actually using the Spreader Turntable!
