Camera zoom/headless mode/throttle sticks

[Bigmattkong]

3 birds with one stone here. I am new to the Mantis Q. I have been amazed so far but it is my first GPS drone. Is there any way to add Zoom? Headless mode? I want to add that I scan the QR code on the Drone and downloaded the app that way to control the Drone. When I tried to download yuneec pilot from the App Store every time I tried login it just said building and never did anything. Wouldn't connect either. Maybe because I already had the other yuneec app from the QR code? Lastly when you push the right or left stick straight in it makes a beeping and I was wondering what the left and the right do in that function? Thank you in advance
