The layout panel is designed to switch between layouts that are open in the application workspace.
If a layout is open on another monitor or in a separate window, it is not displayed in the layout panel.
There are program settings for working with layouts:
Editing the maximum number of open layouts
Enable/disable automatic loading of layouts and undocked windows when entering the application
Enable/disable automatic transition to full screen mode when opening a layout in a separate window or on another monitor
Enable/disable minimization of all individual windows on all monitors when minimizing the main application window
Enable/disable display of layouts in the main application window when closing individual windows. If the setting is disabled, then after closing the separate window, the layout will again be displayed in the panel in the work area.
A description of creating and setting up layouts is given in the section «List of layouts. Search, add, edit».
