It’s not always easy to apply a suitable crop when the image is sufficiently bright as to be quite obvious in the area outside the crop that one is considering.
Request: Provide an Opacity slider for the Crop-tool … to apply to the area outside the crop.
Ah, Yes - I forgot that I had already raised this request !
May I suggest we both remove our vote from the December item (the one you referenced above), and add our vote to this version instead … because this one is not restricted to EA members only - so, it may attract more votes.
