Here's what I would need: the ability to position five nodes in a circular fashion, so that they are evenly spaced.

Intriguing thought. Of course by writing code it can be done

  \foreach \i in {1,...,5} {
    \node[circle, draw] (n\i) at ({90 - 72*(\i-1)}:1cm) {$\i$};
  }

but I'm not sure how to expose that as a UI in a nice way (maybe: if something uses polar coordinates and the user holds shift, then during drag the radius stays fixed, and I nudge towards even angular spacing + multiples of 15 degrees?)

		A simpler way to do this would be for the user to create and place some temporary virtual "grids". For example, the user might create a virtual triangle of a certain size. Or in the case of this request, a circle with n points. Note that these are virtual and temporary items never created in the underlying tikz code (though you may implement them with hidden tikz code). Then the user can do one of two things. (1) Select an item and place it on the grid, and the item gets replicated on all the grid points. (2) Pick and place different items on each of the grid points.

		That sounds like the array modifier in Blender
