I was just thinking. #fediverse really needs a kind of URL scheme which encodes both the origin URL and the fedi "platform", so fedi clients and browsers (perhaps with extensions) can reinterpret the URL and redirect the user to their own instance. This would go a long way to making federated services in the browser feel like one "app".
Perhaps simply adding ?fediapp=microblog or ?fediapp=threadiverse or ?fediapp=videos to the end might suffice, even though it's a bit ugly in the URL bar.
Or perhaps domains can expose this with a TXT record..? Hmm.
