If I'm actively using Google Maps, I'd love for Siri to respond to "get directions to McDonalds" within the Google Maps context instead of opening Apple's.
If their app is open and full screen, search within the app first.
Similarly, if you’re watching a video on YouTube and want to search for a cat video, sure, the voice command should search in YouTube. But if you want to listen to music and have Spotify set as your default music app, it shouldn’t send the request to YouTube Music just because YouTube is open.
