I am a long time Plex user and one feature Plex has that I have t seen anywhere else is the ability to remote control playback from one device to another. This isn’t casting to another device, just remote control.
This feature is invaluable when on a road trip with a kiddo in the back who is too little to control the device himself. My wife can sit comfortably in the passenger seat and pick shows, control playback, and even adjust the volume!
Once playback has started it is no longer dependent on the controller since it isn’t casting but just starting and adjusting the playback.
It would be awesome if Infuse had this feature too! I don’t love the direction Plex is headed and would love to jump ship but I really need this feature for road trip sanity!
