I'd like to offer my suggestions for further improvement which I hope you find useful.
Power consumption (and battery life) in Android phone with *OLED-displays depends from used color theme. If you are interested you may find some statistic here (http://forum.xda-developers.com/showthread.php?t=1882467)
I think that the owners of the *OLED phones will be very glad to see the really dark theme.
I attached screenshot as an example.
