AI Summary: The AutoDarkMode application is not appearing in Windows Search results (classic search bar, PowerToys Run, and CommandPalette), despite individual files being searchable and the program being recognized by other Windows services like Control Panel and Task Manager.

AI Summary: This is a feature request to automatically change the Windows lock screen image when the system switches between light and dark mode. The user notes that the application's existing theme-switching feature successfully changes the desktop background but not the lock screen, as `.theme` files do not contain lock screen image information. The enhancement would require the application to detect the mode change and apply a corresponding lock screen image.
