Offline reading

After each sync, the messages in the period chosen in Configurações → Geral (Settings → General) are downloaded in the background, without marking them as read: Últimos 30 dias (last 30 days), Últimos 90 dias (last 90 days), Tudo (everything) or Só ao abrir (only when opened).

Without internet, the inbox, the reader and the search keep working with what is stored.
