Imira mirrors the phone screen and audio to a Miracast sink - a TV or an HDMI dongle - over Wi-Fi Direct. No app on the TV, no cables, no network: the phone talks to the sink directly. As far as I know this is the first working Wi-Fi Display source for Sailfish OS.

SF-Mail is an unofficial, security-friendly e-mail client for Sailfish OS with built-in OpenPGP and S/MIME. Its goal is to make encrypted e-mail genuinely easy: encrypt, decrypt and sign mail (PGP/MIME, inline PGP and S/MIME), including encrypted attachments. Accounts, folders and messages come from the system mail database, so the app sits next to the stock mail app and shares its accounts. "SF" is not short for Sailfish - it stands for making security friendly.
