Google Messages on Wear OS is set to get two highly anticipated features, according to recent code discoveries. The first feature is emoji reactions, which will allow users to express themselves more creatively in text conversations. Currently, users can only see emoji reactions on Wear OS, but they cannot react themselves. However, a new code snippet suggests that this functionality is on its way, bringing a more interactive and engaging experience to smartwatch users. The second feature is a 'Mark as read' button, which will enable users to manage their unread messages more efficiently. This button will be particularly useful for those who want to quickly dismiss less important messages without having to open the app on their phone. With these new features, Google Messages on Wear OS is poised to become an even more powerful and user-friendly messaging app.
