[Bf-committers] Circular array modifier

I agree that spin tool currently do not create an elevation.
But it has a duplicate option in 2.79 and in 2.8, it was separated in
another spin duplicate tool.
I was just thinking this tool as a node that could be associated with a
falloff node that exists in animation nodes addon.
http://animation-nodes-manual.readthedocs.io/en/latest/user_guide/nodes/falloff/fade_falloff.html
I don't deny that proposed way is more intuitive.
But we could imagine a refactor of current array modifier to use
manipulators as simple as that instead of creating a new modifier.
If a radial array was done with a center defined by a manipulator just
activated with a checkbox added to current array modifier;
will you still request proposed modifier with its 3 methods, 4 values and 6
buttons ?
