Please write it up briefly in the [Features category](https://forum.getodk.org/c/features)! Hopefully it will be as simple as saying that it's like [the selfie widget](https://forum.getodk.org/t/front-camera-by-default/6481) but with a different appearance name (rear-facing?). You can try out the selfie widget in the `All widgets` form that's first in Get Blank Form when you have the default Aggregate server set ([https://opendatakit.appspot.com](https://opendatakit.appspot.com)).
