At this moment you can start an animation by Flow and run it for let's say 50 minutes. By repeating this Flow every 50 minutes, the animation would show like a screensaver.
Would be nice when a LEDitor animation could be assigned to an actual Homey screensaver.
If this is not possible in a user-friendly way, there could be a separate "LEDitor screensaver" page to make animations act like a screensaver without being one.
