Rather than just using the “Select Center of Circle” to determine the diameter of the circle within a circular array, allow the user to specify the diameter (or radius) of the circle to be used to position the elements.
This would allow precise spacing.
It would also provide a quick workaround to the Tangent problem posted in a recent post (Feature Request - Tangent Lines to Circles/Arcs) because you could easily lay out lines around a circle of a specified diameter and they would appear tangential to that circle (which you could match and align to another circle, if you wanted to).
