The grid toolbar on the layout manager can now be displayed on the main viewer, making it possible to change the current frame layout without requiring you to open the layout manager. By default, the grid layout toolbar is hidden. To display the grid toolbar, click on View/Toolbars/Grid Layouts.
On the grid toolbar, two 2-up grid layouts exist. One is a side-by-side orientation intended for use on landscape monitors. The other is a top and bottom orientation, intended primarily for portrait monitors. Both are available for either type of monitor.
