Wow, this is very cool. Nice work!

I would like to make some feature requests if you're open to it:

1) The web site instructions should be clarified to say the word "simultaneously" when referring to the button presses. If it doesn't say that, someone might think that they need to press the left/right buttons AFTER holding the bottom button. This only changes the track without enabling/disabling voladj.

2) Since you've shown that you can write to the display with the games, how about writing a message: "Volume Adjustment Enabled" or "Volume Adjustment Disabled" when the change is successful?

3) Could you compile a separate version which has Voladj enabled by default in both home and car locations (for me), as well as a version which has it disabled by default in both home and car locations (for audiophiles)?

Still haven't seen the surprises, yet.
