- Updated the ChatWindow component to provide clearer instructions and actions when no conversation is selected, improving user guidance.
- Redesigned the MenuBar to display session timeout information more effectively.
- Enhanced the SearchView component with a more user-friendly country selection using a Multiselect dropdown.
- Improved the UserList component to display user age and gender, enhancing user profile visibility.
