Fair enough, Andrew - that’s well explained, thanks.
[ I usually make a point of “pushing back” on these topics (of which there’s been many similar, since CPs were first introduced), as some users are unfamiliar with the actual way in which CPs select those parts of the image that will be corrected - - - I see that this does not apply to you.]
Yes, I’m completely with you on this one … I have an outstanding UI improvement request here that argues for ability to adjust LA sliders using the Up/Down,Left/Right cursor keys - for ease of fine-tuning AND consistency with ALL other PL sliders … as of now, it has 17 votes.
