LCD brightness: auto

[gotar]

Dealing with hardware, which - well, do things with light, I really miss the feature of automatic adjustment of LCD backlight. Of course the lens can be closed, one might meter the light of some deep cave in shiny bright day, but many situations are perfectly suited for this to happen; being outdoor we need bright LCD to be seen in full sun, or dimmed when it's night. I often find myself blindly increasing backlight barely seeing the display.
