Add a gradual transition to nightlight instead of turning it off immediately
When it's early in the morning, nightlight turns off because the sunrise already happened but I feel like it's still too early to turn it off completely (the screen looks so blue). Something similar happens in the evening..
So I think it would be great if you added a gradual transition (1 hour long or so) from the warm temperature to 6500K. If you need an example of what I mean you can check f.lux, it has a slow gradual transition that lasts 1 hour.
