[Gardoon]

Ideally, I would like to make it configurable. Give the user the option to either turn on x number of seconds before the end of the round, or stay on (full backlight or backlight off) for the whole round, or remain off and just do the beeps as they are now.

I would also like these features to work when the user turns off the screen and when the device auto-sleeps - though I haven't played around to see if the two are actually different.
