Customize window settings by using the View tab.
Keep main library window in background
When selected, the Editor opens on top of the main window. If not selected, the windows behave independently.
Note: You must restart Author for a change in this setting to take effect.
Save window position and size
When selected, these options save the position and size of each window when it is closed. The next time you open the window it will appear at the same position and size. These settings are saved against the currently open library, and so will vary from one library to another.
Preview pane position
Sets the Preview Pane Position relative to the Library Explorer's object list. Set the pane to display to the right of the object list, or below the object list.
