May be allowed to select what is to be kept by marking it around with a pencil tool and delete the rest

We need a means of marker tool to select the area or complete background area to be erased. We then need to be able to have the choice, of replacing the background. In this case, replacing it with transparency. The word "transparent/-cy" is currently rejected by AI as a no-go zone marked in red. We need to have this fixed. Even from the edges outwards, the image/s needs to be pristine and transparent. Us then able to overlay this particular transparent image as a first, second, or third, or whichever layer is calculated in use, to be displayed accordingly.
