For when the auto function doesn't work
I too miss the manual LatCA sliders; The auto CA check box does work well...I haven't, and will not soon, bother to make a thorough comparison between the LR3 manual slider and the new Auto correct feature. It is possible that the new Auto correct is doing a better job over the whole image. But there was something much more satisfying about being able to adjust through and past the correction. Kinda like being able to rack through the focus on a camera lens, instead of pushing an AF button. More control is, no..feels better.
I do appreciate the automatic option. This is something Nikon has been doing for a while in-camera and in the NX converters, and has worked great most of the time, even with 3rd-party lenses.
But auto fails with bad cases of lateral CA, like when using add-on macro diopters, wide converters, or with some vintage lenses. The same with LR4 and Nikon. For these the old manual correction is better. Please bring the manual correction back as option.
As _Sem_ wrote it can be useful with some old lenses adapted on a modern camera (I sometimes use vintage Pentax m42 lenses) but it is almost a "must" when trying to correct images from digital pocketcamera's that people send me. It's not convenient to do so with each image in Photoshop's lens correction filter. Just give us a chance to overrule the automatic option.
I have found that when I go back to edit my old JPGs using Process 2012, the Chromatic Aberation check box doesn't really work on some of these old JPG photos. The Process 2010 Chromatic aberration sliders did work. So, I request that Adobe provide both methods in Process 2012.
Automatic is nice idea.... but in complex case, the manuals sliders is best/better (works finest).
It is NOT complex CA keep this 2 modes (keep the Automatic CA in first page), and just add the two sliders in the same location

Very easy to make (updating), and many users very happy
Just read some forums and see many comlpaints of users about Removing CA sliders
If Programmers of Lightroom want know this...wonderfull
