Pigment.O plugin

Let me ask with a pic.


These should be related to pins since if PIN is turned on in the settings, these boxes appear.
In the Luma panel alt+LMB is supposed to select pin:

  • LMB : Select color
  • Shift + LMB : Zoom color
  • Pen Pressure : Zoom color
  • Ctrl + LMB : Change the third axis ( Luma )
  • Alt + LMB : Select pin (HERE)
  • Alt + RMB : Edit pin
    But nothing happens when I do it on the panel.

In the second picture, mixer sliders are activated. But I don’t know how to choose the two colors to be mixed?
