I always use your "lights on" feature, its a great way to naturally brighten an image at the click of a button, however on a black product it doesn't work so well which is fine. I suggest when bulk editing an image set for a lights on button which applies to all images in the set but if you click on an individual image you still have the option to turn it back off again. Sometimes 4/5 images require "lights on" and the final does not. This would be an awesome feature to add and would speed up editing even more!
