Req: A Defringe adjustment layer

[photoken]

There are times when the RAW images from my LF1 show noticeable colour fringes in parts of the image. It would help if PL had an adjustment layer to remove those colour fringes.

By way of example, here's how PaintShop Pro handles it: Their tool is their Chromatic Aberration tool, but one can specify any colour by selecting the colour in the dialog window, up to about a dozen colours:

That method does work, but a far better method is the one implemented by RawTherapee, where the colours are specified by dragging "anchor points" on a Hue spectrum:

The anchor points have control handles, like the anchor points of a vector shape, that allow changing the amount of "roundness" at the peaks, and the anchor points can also be dragged left and right to precisely target the colour.

Maybe we should start with some test pictures, experiments and an action to find the best way to treat fringes?
I have something like that on my eternal todo-list, once a nice recipe was developed in a dslr-forum.
