Dark mode affects both the UI and styles for cards. Dark mode can be previewed to see how it affects cards by going to a note (or add note) and toggling Dark Mode from the drop down arrow.
This kills custom font and background color customizations users might want to keep. I only want dark mode for the menu UI, not for cards.
In the app preferences window, please add another checkbox box, nested under Night Mode, that makes it so Night Mode only affect the UI and not cards.
