The camera stays the screen; the record button stays under your thumb. Preflight moves into the drawer: peek says if you are ready, pull up for the checklist, pull all the way for every stream detail. The drawer scrolls, so new fields slot into a group without changing the screen. Drag the handle, or tap Details.
One rule: when the screen spans the crease, the drawer becomes a page. No detents to drag; preflight and details get the start page, the viewfinder gets the end page, and the record button sits at the foot of the console. In tabletop the bottom half is the drawer, and once you are on air the top half turns into a desk you can read from the driver's seat. The cover screen is the phone design as-is. Same controls above drive these.
