Add an option to redirect some domains to more privacy-focused alternatives.
I'd find it a really nice feature if the user could define a redirect in the domain settings.
For example redirecting reddit.com to old.reddit.com as it doesn't require JS or redirecting YouTube to Invidious, a private YT frontend. There's also Nitter, a JS-less Twitter frontend.
It could be implemented in the domain settings or in the global settings.
