All kinds of shit.

I'd make locking the phone while the flashlight is operating require pressing the lock button again to wake the screen with no exceptions, so the screen no longer shines in my eyes reducing the effectiveness of the flashlight, and stay palm input stops opening the camera.

I'd hook screen time management of my children's devices—which I perform on my own device—into FaceID instead of requiring a stupid passcode.

You don't have to go far to find areas where iOS could use some customization. But if it's Apple's code, the most useful adjustments are off limits.

Jailbroken iOS was a fantastic platform for the first 9 major releases or so because it had that kind of stuff in it. Now it's "throw a suggestion in the box on our website and we'll ignore it in the order it was received."
