Ideas for document scanner

This under insert >> Camera

1. The current capture algorithm is too quick. It identifies an image before the camera has even focused. 
2. After capturing, there is no way to zoom in and check the quality 
3. Cropping only allows decreasing the size and not including some of the image that was outside green rectangle

Without being a troll, I would just like to point out all these functions were supported in the older version

The embedded image scanner is unusable for me and I have to use Scannable or other apps, which is annoying
