Each document in a Scrivener project is associated with a synopsis, which can be viewed as an index card on the corkboard or as a row in the outliner. Using Scrivener's virtual corkboard, you can get an overview of your project and rearrange the documents using their synopses only. And if you don't like the corkboard background, you can change it to one of your choice, or just a flat colour. You can even make the index cards look more like Post-It notes if that is your preference.
