Technotes/HiddenPrefs.md
See AppDefaults.swift for the app’s preference keys, including hidden prefs.
Hidden preferences tend to be named for a person:
The main window doesn’t display its title, partly because it looks cooler that way and partly because it’s redundant information.
The downside to this is that title-less windows do not allow the toolbar to show button names on macOS Catalina. (This is an AppKit thing.)
To turn window titles on, set KafasisTitleMode to true.
Set CorreiaSeparators to true.
Set GruberFeedDoubleClickMarkAsRead to true.
Set DevroeSuppressSyncOnLaunch to true.
