To be honest here, I also like that warning screen.
It something you really never notice anyways, because if you're used to the Wii now, you should know to just hit A when the Wii loads. It's not like you read that everytime.
But this looks really like a great app. I bought a Wiikey already so this has no use for me. Unless I want to remove the health menu which I don't. BUT if someone came up with a way to edit the health screen, such as putting a background of a game and some sound effects saying "Press the A button" then it would load to the Wii menu, Now that's something I would update to.
