Logic of work:

• An exclamation mark icon  appears in the "Variables", "Files", "Web elements" and "Win elements" panels at each unused resource in the scheme
• The color of the exclamation mark is #FF8000
• Location: The point of the exclamation mark is at the same level as the letters of the resource name
• A resource is considered unused if it is not specified in the input or output parameters
  
• If the resource is used in the robot scheme, the icon is not present
• If the user removes a resource from the scheme and it is no longer used anywhere else, the icon for the resource  appears in the panel
• If the user created a resource manually via the panel, the icon  appears immediately next to the created resource and remains until the resource is used in the scheme
• If a resource is used in a disabled action, the icon does not appear on the resource
• If the user adds an unused resource to the scheme, the icon  disappears
• If the user has specified a property for an unused resource, the icon disappears. The resource becomes a used one
