What do the workflow bubbles mean?
When a style is first created, the workflow pages have a bubble to the left, indicating the Status of the page.
As the pages are edited and the page status is updated, the bubble reflects those changes.
The specific work that has occurred, or why a status was given, is found directly on the page in question. But the color of the bubble is a quick reference for all parties working in the style folder. The username listed in the_ Assigned To_ field is usually the one responsible for managing the page status and colored bubble indicator.
