Retro UI Mode

• For pilots who appreciate a bit of nostalgia, we are exploring a "Retro UI" mode. This setting would reskin the Perflight interface with a classic aesthetic, giving the application a distinct look and feel compared to the standard modern interface.

• This is an extreme and somewhat wacky idea which could give way to multiple app “themes” of which “Retro” could be one?

• Save this for a rainy day when we literally have no other problems to solve
