Hi, I love the color zones adjustment tool, especially for scanning Kodachrome. However, I find the way to manipulate it with the control points a bit flawed: I'd expect the shape of the adjustment curve to be translation invariant - meaning that I can pick an arbitrary point on the x axis and shift if up and down. However, due to the discrete control points, this is not true - if I am exactly on a control point, I get overshoot in the opposite direction about 1-point away on both sides. If I happen to want to adjust the curve in between two control points, it behaves very differently (no overshoot, but much slower adjustment, somehow). I am aware that the fact that I can change where the control points are, but that seems tedious - and seems at best a cumbersome workaround for the unpredictable behavior.
Is this something that the developers would be open to changing? Not sure if one should try to rescue the current idea (maybe auto-align the control points with the x-coordinate that one tries to change?) or if a totally different idea would be better? Martin
