You can display and edit more Fred4 pages of the same edition in one multi-page view in a content tab. Pages are displayed in a grid, each with own "paper" ("paper": a background with customizable color) and pasteboard (with configurable size and color - the same for all pasteboards).
The following screenshot shows a content tab with two pages in the same multi-page view.
