Each document revision has a subfolder Derived Revisions that shows which revisions are directly based on it. This information is shown in the content pane, on the right in the main window. When a Document Revisions folder is selected in the tree-view, on the left in the main window, the information for all revisions of a document are shown in the content pane on the right. When the Derived Revisions folder of a specific revision is selected, the revisions based on that revision are shown in the content pane.
