As per the native Gradient panel; deletes the selected stop(s), with the limitation that gradients must contain at least two stops.
When enabled, the dragged stop will have its location snapped to multiples of the Snap Value (0.5%, 1%, 2%, 5%, or 10%), except when it is being snapped to a centerpoint. Unselected stops, when rippled, are not snapped. If multiple stops are being dragged, their “non-snap” locations are calculated and then rounded to the nearest snap location. Thus the spacing between dragged stops may change if they were unsnapped to begin with. To snap selected stops without dragging them, see Adjust Positions Section: Snap Button. To temporarily disable snapping, hold down the Command/Ctrl
key when dragging a stop.
When enabled, the dragged stop will snap to locations that are halfway between the stops on either side of it, with magenta arrow annotations indicating this. Snapping to a centerpoint takes precedence over the grid snapping (i.e., the center snap value may not lie on the current snap grid).
