Hello,

I have two question regarding slice viewer (red, green, yellow):

1. Is it possible to reset change in intensity which is made by mouse dragging to default values?
2. Is it possible to set slice intersections to clicked position?

Reset image intensity display window/level. Go to volumes module, below the color presets, change `Manual W/L` to `Auto W/L`. From Python script:

```
vol=getNode('MRHead')
vol.GetDisplayNode().SetAutoWindowLevel(True)

```

To prevent accidentally changing W/L, you can click the “lock” button next to Window/Level label.

Hold down `Shift` key while moving the mouse. No need to press any mouse button. Works in both slice and 3D views.
