Very low priority, and already mentioned in Slack before, but just wanted to put it here for completeness.
It would be nice to have a native dark mode, especially for maintainers. Its really hard on the eyes at night having to read through suggestions. I have tried addons before but sometimes I have to turn them on and off to see certain changes, so a native dark mode would be nice. Also IOS you cannot really put a dark mode addon using safari, so a dark mode would also help there
