Finer undo when acquiring image

[axlgit]

Hi,

at the moment the flow before sending an image to the server is the following:

1. acquire the with the camera;
2. adjust the borders of the quadrilateral;
3. visualize the cropped image and and select whether to convert the image to black and white.

If at step 3) I want to go back the app brings me to step 1) instead of step 2)

Sometimes I end up in a very good shoot but I change my mind and I want to resize the cropped image but 'm brought back to the acquisition step.

Q: at step 3) would be possible when pressing the back button to go to step 2) instead of step 1?

Thanks,

Alex
