The Display Options tool shows you the different choices available. The default option for accounts is called FORM FACTOR. With this option project thumbnails are displayed as variable height images using a "Masonry" display. Individual projects are presented with all images, files and text on a single page. Each choice in the selection bar gives you a visual preview of how the pages work, along with a short text explanation of how it works. Your current display option is labeled as "(currently selected)".
