Night theme

We really need a night theme badly, please! The white/grey/charcoal theme is fresh and modern but when flying at night it burns your retinas. Could you come up with an inverse theme, please? This would include:

background: black
headers: slightly less charcoal than they are now so there is contrast with the black background
header text: light grey
text: light grey
other header text, flight headers, etc could be: red, orange, sand, green

You would also need an easy to reach toggle on the main screen and especially the Flights page.

Thanks!
