Which device are you using? Samsung Note 9 What problem do you see this solving? Every other Android user who also owns the Desktop C1 client probably wishes for C1 mobile as well.. When was the last time you were affected by this lack of function...
I am a portrait photographer. When I use the desktop version, it is always helpful to put multiple images side by side to help the client compare and pick the image they love to have retouched. Would love that on the iPad version.
