Hi,
You first sweep through the shots from a session in Rate & Review, and then start working on the selected ones in Edit. But I quite frequently have the need to adjust the ratings during editing, for example when a shot doesn't work out after all and need to be dropped from the selected picks. It's clumsy to swich mode to Rate & Review to do this, and then back to Edit. Rate & Review provides the ability to change the star rating and flags by swiping up and down in the left and right parts of the picture. These gestures does as far as I can see not conflict with anything in the Edit mode, except when using tools like Crop or Masking. I propose adding these gestures to the Edit mode in all tools that doen't use gestures in the picture.
