There are three main areas of Cascade's interface. The menu bar is the dark blue bar across the top of the screen. Most notably, this is where the “New” menu, search bar, and “Quick Links” items can be found.
The navigation area on the left part of the Cascade screen replicates the menu that will be displayed on the left side of the published site. This area is also the way to travel through internal Cascade web pages for editing in Cascade.
The area on the bottom right of the Cascade screen is context sensitive. When pages are clicked, the selected page shows up in this area. When a folder is clicked, it shows the contents of that folder.
