optional on_at_startup

[Shadow]

Would be very useful to have the tracking screen "always on at startup" as an option.
I always have to click "view" then "tracking" every time I start the program because I want to make sure the dot is in the center area before I launch a game.
Might as well make the "heads" and "guages" optional too.
Other than that, looking good.

I would like to second that and expand it to all the windows.
