• The items on the page are color-coordinated so you can quickly distinguish class display ads (orange) from line ads (yellow) from classification headings (green) from fill ads (red).
• When all the ads from a classification are on the page, the classification gets a strike-through so you know they're all accounted for.
• To flow liners you select the classifications and click the Apply button. You can flow ads forward or backward on a page.
