The debug dialog is temporary and it only shows in debug builds. I was trying to collect data on screen size and density for various devices. I might leave it there a little longer (still only for debug builds) until we're comfortable with the UI across all devices.

Yes, we need to group these settings a little better. I think it's just a matter of shuffling things around. One *Root* setting window that branches off into *General*, *Vehicle*, *Joystick*, etc. I will wait for @DonLakeFlyer  to be back so we can figure this out.

In the mean time, I will merge this in as is as it provides a service regardless.
