Dato curioso: la única interfaz de correo electrónico basada en búsquedas de Opera es anterior a gmail. Terminé cambiando de nuevo a Opera Mail (anteriormente llamado "M2") después de tomar la decisión de cerrar todas las cuentas de Google. La administración de contactos, la importación / exportación y la sincronización (inexistente) apestan, y no hay soporte para el cifrado, pero Aparte de esos inconvenientes, estoy bastante contento con eso.
