This has been brought up before but I don't recall a good case being made against using the blacks, exposure, and brightness for setting these things, other than being used to doing it a certain way. Is there some compelling reason for wanting these things on the curve instead of as basic adjustments (I mean other than being used to it that way)?

I suppose we all have our preferences. I enjoy the alt + click option to view the blown highlight/blacks on the white/black sliders. I also find it more convenient to use at times. Finally, I enjoy multiple options when working with pictures. Depending on our Sad, Happy, Confused Icons to choose from, our decisons on our use of options are decided on them.

I doubt too much gets decided based on happy/sad faces, but its sometimes worth trying to make a case for things you think would be improvements...

The white-balance eyedropper in LR / ACR functions similarly to the midtone eyedropper in PS curves and the RGB channels are not split in LR's curves.

The LR-toning blackpoint and exposure sliders in conjunction with the clipping indicators perform the luminance function of the PS curves black and white eyedroppers, but an eyedropper to aid in dark and light color-neutralization of the LR split-toning adjustments would be a great help.

Good idea, Steve - Too often I have blue or aqua casts in the shadows that I fix using split toning: always painstaking. Maybe a black, white, and neutral point, to set the split toner's shadow hue/sat, highlight hue/sat, and balance, respectively - is that similar to what you were thinking?

Overall neutralization is done via the WB controls so no need for any midtone eyedropper.

I wasn't sure if Roy's request for black- and white-point eyedroppers in the curves area was more about luminance levels or color neutralization so I brought up using eyedroppers for Split Toning.

Regarding Split Toning:

The Balance slider sets the point where the tint-adjustment gradient changes from the shadow tint to the highlight tint. I'm not sure if the Balance could effectively be set via an eyedropper, but it could be tried to see if it is useful. The Balance slider should remain.

Split toning can be used to neutralize shadows and highlights but is ridiculously cumbersome. It seems like a simple shadow-neutralize and highlight-neutralize eyedropper pair would help immensely in setting the H/S Shadow Tint sliders.

For people who are using the split-toning to adjust but leave a color-cast then a more general eyedropper operation would be to match a highlight and shadow color rather than making them always neutral although perhaps letting people tweak the sliders after using an eyedropper to neutralize might be good enough.

It is possible that a shadow-sampling eyedropper is ineffective for adjusting a shadow-tint because the effect of even a small amount of color-noise would throw things off in a similar way to using a very dark area to set the WB, so some work might be needed to help with finding a reasonable average black-point sample value but it should be tried, or an explanation about what problems where have been and why it doesn't work, given.
