We use quite a few images in our mailers. It can be tedious scrolling up and down looking for these images. Not sure how this would affect others or your design code or functionality, but it would be nice if the slide area on the left would be able to expand to see more then 2 images per row. I compare to Adobe Bridge where the size is adjustable from 1 column to as many columns as needed. I've attached an image to hopefully illustrate my idea. Thank you for your time and keep up the great work.
