Camera Raw: revert to previous behavior in + - on Local Adjustment
Previous versions of ACR, when using adjustment brushes (K) used a "+ or -" to quickly set an adjustment of +25 or -25 for any of the adjustment options (selective edits).
Not only has that disappeared, but also when clicking a new/different adjustment, all previous adjustments would be "zeroed out". Now it is more cumbersome to "zero out" previous adjustments (although I finally figured out how to do it).
Personally, I find the old method far superior and specially, faster to use.
I certainly hope you either go back to the old way, or at least provide the capability to operate that way if desired.
Other changes, such as the new interface on the right side appear to be worthy improvements
