if i read this right, you're saying that you wouldn't want the display
to stay colored with the backlight off?  what's your reasoning?  the
screen is transflective whether in mono mode or not.

bear in mind that this really only kicks in when the surrounding light
is bright enough that you literally can't tell whether the backlight
is on or not.  currently there's no way to disable it.  that will change,
but i'm not sure what form the UI might take.
