An option for adjusting the time span of the gradual transition for Night Light
Now, it seems like the time span for fading to night mode is around 1 hour - 45 minutes. For me, this is too short, as I want the gradual transition happening much slower. A simple number for how many minutes the complete fade from no redness to full redness would be enough.
I don't think there needs to be a fancy or interesting GUI. Just an input box, maybe a slider.
It could even be enough to only allow it to be edited in a dconf-editor.
