We recently cutover to a new approach for realtime data and one of the things I was thinking about using it for is the ability to push actions down to ‘viewing’ devices.
There’s a feature request for it here, but it hasn’t picked up much interest from the community:
As you may be alluding to, having a photos integration plus the ability to dynamically change which dashboards a ‘viewing’ device is displaying would let you keep everything in SharpTools without needing a separate Kiosk App or Screensaver Site.
