Change Ruler Size

You can change the height of the Sensory Ruler by adjusting the slider. If the slider is set to the full level, the Ruler will colour or tint the whole screen. So Sensory Ruler for Mac becomes a full screen overlay in this situation. When this the full screen tint takes effect by moving the slider to the full right, the background colour Above and Below the ruler will not be visible.

The screen shots below show an example of a narrow ruler, a mid size ruler and full screen tint.
