Tateau,
I'd like a brightness adjustment for BBLight.
My BlackBerry Bold can go down to 1% brightness using the BlackBerry API call, but the BlackBerry Settings->Screen only goes down to as low as 10%.

The 1% mode is used in the clock BedSide mode, which is wonderfully dim -- perfect for usage in the bedroom without waking a spouse up. And very easy on the battery too.
