I admit: I'm a display hog. Whether I'm checking blogs or reading this forum, I run the display all the time. And it eats my battery.
The thing is, I keep my brightness at the lowest setting. But I could really go lower in most indoor situations and at night.
I know that the brightness can be forced lower still, as the dock has a "extra-low brightness" button. See it for yourself: get there from the clock, and then hit the sun button. The display goes really dim.
So how can I get the display to go lower in normal situations? Can we add an "extra-low brightness" setting to the power widget? Is there another widget that can do this for me? BB does a great job conserving battery when the phone isn't running, but I think this could help a lot when I'm running the display.
