Forgive me if this has been covered before. I couldn't find anything.
Is it possible to add a [range] custom tag to the unitframes showing how far away you are from the target. It could (in my imagination) be used both on the player frame and target frame, whereas on the player frame it would not return anything if there is no target selected. I saw the aguf_rangecheck addons, but not sure if any of these cover this particular feature.
