I've been having a lot of fun trying to port Rockwork back over to Sailfish. The daemon's running, and connecting to the pebble (v3 firmware). Music/volume control works, and notifications, which have lots more flavours than the old v2: telegram, whatsapp, hangouts, which i've mapped over to the android and native apps where present. I also managed to find a bit of code to decode the notification actions, so you can now open the email on the phone from the watch.
