dark mode definitely an important feature, but simply adding a dark background is not a dark mode, the color matching of various components, text and code blocks also needs to be considered
we won't start developing until the design is ready, but dark mode is definitely on our roadmap
the roadmap is expected to be released next week, please stay tuned
