I’ve been playing with W0CHP’s Pi-Star Digital Voice Dashboard and have an early contender for a nice dark mode display. Settings below can be used as a starting point. The Look and Feel screen is a very nice upgrade to the traditional Pi-Star, and there is a lot you can do to tweak the look with dashboard colors.
