It would improve efficiency and user experience if messages were automatically marked as read when opened, with the option to manually mark them as unread afterward if needed.

This mirrors the behavior on iPhones (and possibly other platforms), where a user can revisit a message and choose to mark it as unread if they want to follow up later. This approach feels more intuitive and less time-consuming—especially for users who handle high volumes of messages daily. It eliminates the need to manually mark every message as “read” after reviewing it, which can be tedious when no response is required.
