Dark mode with light mail messages
Monterey seems to have lost the option to view messages in light mode while the system is in dark mode. It seems so logical to have the system in the background and the messages (most of which have been created to work in light mode and which invariably look more natural in that mode) clear and prominent in the foreground.
I'm sure some like to use dark mode in darkened rooms to reduce glare, but for many of us, it enables us to focus on the content (just as it does in Safari, Pages, Keynote and most other applications).
There used to be a check box to enable this. Is there any other way to reinstate it?
