 ## User Interface Glimpse
 
-The example screenshot below shows GpgFrontend running on macOS, illustrating
-its clean and modern interface design. Interface layout, fonts, and colors may
-look different on Windows or Linux, but the core features and workflow remain
-consistent across all platforms.
+Most of the screenshots in this manual are from the macOS version of
+GpgFrontend, as primary development and testing are conducted on macOS. This
+approach ensures consistent screenshot quality and a unified visual style
+throughout the manual.
