It is possible to float the Document Viewer to a new position inside the application as well move it anywhere on the screen outside of it. Moving the Document Viewer outside is useful if you have dual monitors. For example, for Validation, the Batch Content and Current Problem pane are on one screen, while the Document Viewer pane is on the other. In order to float the pane, click its header and drag it to the desired location.

To maximize the pane, double-click its header.

You can automatically hide various panes so they collapse into a tab wherever they are docked. To auto hide either of these panes, click the pin in the pane header. Click the pin in a pane tab to return the pane to its original location.
