I constantly use the HUD color picker for selecting color. The shortcut is Shift + Alt + Right click. This lets a hue strip or color wheel pop up to quickly choose colors on the fly. This shortcut used to work for both the brush tool and the gradient tool. Below is a screen grab of the HUD color picker wheel.
Ever since version 24 has been introduced this shortcut no longer works for the gradient tool.
I have been in touch with Adobe numerous times, but the recent updates still have this bug. So, I am still using version 23.
Is anyone else struggling with this?
