There seems to be no way to change the default gray background in the GUI. It would be nice to "Invert" or swap the foreground and background colors for the entire GUI and not just the Subject field in Settings-->Color/Fonts (a la "Dark Mode"). Or, perhaps a Dark Mode under View-->Application Look.
Hi there. Any progress to report? I am a Loyal user since 2007. I also have a visual impairment. For accessibility's sake, please consider a dark mode option. Thanks. Geep
