In the evenings it’s good to prepare your body for the upcoming sleeping sessions by dimming the lights at least an hour before going to bed. Unfortunately there are often reasons to quickly check something on your phone or computer and, by that, you get blended by crazy white User Interfaces (UIs) – the screen brightness often automatically changes these days already. Only on Google Maps Navigation mode I noticed that also the UI theme changes when it gets dark but e.g. your browser or your operating system UI usually don’t change automatically.
For this reason I am switching those UIs to a dark theme which usually is okay during the day, saves battery and is much nicer to control during the night. As this is not a no-brainer for every tool I am collecting how to do this for tools I use in the following.
