I didn’t know there’s a built-in dark theme. Thanks, I’ll use it.
By “Dark Mode support”, I was primarily referring to the behavior where an app automatically switches between light/dark theme based on the macOS system-wide Dark Mode setting. Having a dark theme is very close, but it requires the user to switch to it manually (and also requires knowing that it's possible to switch; case in point, I didn't even realize DevTools had its own separate theme).
