Re 3.: I think that's a terrible promtp. The prompt says, my settings might be outdated and I should switch back to Google as a search engine. What's the reasoning here? Why is implied that the settings are outdated if I use a custom search engine? No other settings are checked/affected by this prompt, so why frame it as a settings issue at all? Re 4.: Why silently, why not a prompt here?
