Implement a "dark theme"

Just following up here that a dark mode would indeed be wonderful, and the "sync with system" option as seen on symfony's site would be a welcome automated feature. In general is D.O looking to move to a new theme other than bluecheese with the next major upgrade? Is there a good page resource for either of those - D.O's upgrade plans and theme development?

Would also love to get some darkcheese.

Just chiming back in that I believe some Evolving Web folks are working on a revamped design for D.O - not sure if a dark mode is being included there, but maybe?!

Yeah, there is a new evolution of Bluecheese happening in 2.x branch. This is used for new.drupal.org and, when ready, it might be rolled out to api.drupal.org too.

The codebase has changed immensely from what we have in 1.x, so any new efforts should go there. However, 2.x is right now in constant progress, so I'd suggest waiting some more time before even attempting anything like this.
