As title implied, I want to request @theymos for a night mode/dark theme to make the forum less stressful since pure white is very stressful in the eye. I didn't notice this on my old monitor but it bothering now when using a wide montor.
Install BPIP extension to your browser, it brings a lot of useful stuff. (see more:

And you can choose a theme for the forum, there are also two dark options.
Imho this is the easiest way to add dark theme to bitcointalk.
