@grandevel Dark mode is definitely something that's on our roadmap, but there are potentially a couple of infrastructure-y things that we'd like to do before getting there. You're more than welcome to use the existing theming architecture to build a dark mode for your team / product, but I imagine that ours (what Evergreen will provide out-of-the-box) will be informed by the specific needs for our app(s) internally. We haven't started on it yet, but when we do - we'll let folks know about it in here. cc@kamebkj
