First a bug when the browser load a slow page the "wait page" is white (in dark mode it's annoying and burn my eye when i'm in the dark ^^).
Feature wanted.
It would be very amazing if you're implementing a way to force a dark mode on sites that don't have one (via user action or automatic with the browser settings) (like darkreader on chromewebstore).
While maintaining a list of your own sites and sites already having one.
And of course let the "default" mode of this feature link with the choice of theme of the user, if the user choose light in system, this feature disable herself.
