Night Mode / Screen Dimmer

[docsmooth89]

I would like to use my 8525 in place of an alarm clock on my nightstand. But when I have it upright in a dock, the backlight is too bright to function as a night time clock, even when on its dimmest setting. Does anyone know of a way to dim the backlight lower than its lowest setting the backlight control panel? Is there are program similar to the "night mode" that some astronomy programs so you can use your device without affecting your night vision. Vito Astronavigator II has such a feature, but it only works when Astronavigator is displayed. If you switch to the Today screen, the display returns to the normal brightness setting.

Thanks.
