P: Let me use the crop tool in reference view

I find the Reference View very useful. But I’m missing the crop tool there.

For example when I’m using a handheld camera to make portraits the camera angle differs somewhat from frame to frame.

As I often put together several photos with different expressions on a book page. Then it’s important to be able to control the crop precisely. It would be very convenient to be able to use the crop tool in the reference view to make the crops fit together.
