TOUCH ID SUPPORT IN THE NOTES APP
Apple has drastically improved the native note-taking app in iOS 9, and is continuing to build on it in iOS 9.3. Soon you'll be able to secure all your notes with a password or fingerprint. There's also better sorting based on creation date, modified date, or alphabetical order. Hopefully, this is a sign of system-wide Touch ID support coming. For instance, it'd be even better if we could choose to lock an app on our end without having to wait for the app developer to implement it.
