The Favorites dropdown menu displays commands that you have selected as favorites by clicking the star icons next to command names in the Advanced Settings menus. This is useful because it allows you to change the parameters of frequently-used commands without returning to the Advanced Settings menus.
In the example below, notice that the star icon next to the Light Source command in the Camera Setup menu is selected. This causes that command to appear in the Favorites editor in the left panel of WebLink's Setup view. Commands that are displayed in Favorites can be configured in the same way as commands in Advanced Settings.
