Boards feature request to view or delete without placing

I like how the boards allow you to pick picturesto communicate ideas. However, it does create a bunch of images that are totally wrong, or close but not what I wanted. I'd say 95% of the images are not the results I wanted.  It would be nice to have a "x" in the corner to remove them from my timeline. I would also like to have a button <-> to expand them larger to decide if I want to place them on the canvas. The thumbnails are too small.  I currently have to add them to the side of the Generate Image panel and zoom or move to see them.
