The Gradient Editor dialog, which can be extracted when you click gradient itself, is used to modify gradient. Drag top Opacity Stop if you want to lengthen opaque portion of gradient. To decrease opacity, just drag white Opacity Stop. There is a small diamond that appears between stop markers called Gradient Midpoint. This midpoint can be used to adjust smoothness of gradient by simply dragging it left or to right. If you drag it to left smoothness of gradient is increased and when you drag it to right smoothness decreases.

To edit multiple layers, group them first by selecting them and then type Command-G or Control-G. If you want to ungroup multiple layers, just type Shift-Command-G or Shift-Control-G. If you want to modify you’re your work, use Gradient Editor. Double click gradient layer and choose new gradient style.

You can make your own gradient and add it to pre-defined gradients by saving it and setting style scale and angle of your gradient.
