Many times my design drawings have light gray images that may not be part of my work. I have been saving these files to a new name to keep the original in case I need this info later on, and then remove these ghosted in images to make my work clearer. Before I remove them, they are changed to a new color so I can identify if they have any information I may need.
Is there a way, than once if change this to a new color and identify that I may not need this info, I can put it all on a new layer and turn the layer off? That way if it turns out I do need that info, I can turn the layer back on.
