I added nostr login to advanced nostr search. You can log in with just an npub, so it's easy to switch between accounts. The only purpose to log in is to auto fill the npub field. When you switch accounts, the npub input field automatically updates. If you load the page and the URL contains an npub query param, the npub field will be filled in with that npub and not the npub that is logged in. That way sharing links for specific queries works the same whether you are logged in or not.
