Romain Hunault expanded the Murena app catalog and unified branding within the ente-io/privacypack repository, focusing on catalog management and data consistency. He introduced new Murena alternatives and standardized naming conventions for core applications such as Email, Gallery, Notes, and Calendar, consolidating them under the Murena Workspace identity. Using JSON for structured data management and front end development skills, Romain ensured that app assets and logos were consistent across the catalog. This work improved catalog diversity, enhanced user discoverability, and established a foundation for cohesive branding, resulting in a more maintainable and coherent application ecosystem for Murena users.
