The Favorites list is useful, for example, when there is a need for comparing concepts. In the Concept Details panel, the Concept Summary tab shows a star. When it is selected, the concept is automatically added to the Favorites tab on the left. 
Clicking on the star will send the concept to the favourites list. Also, it is possible to add concepts by dragging and dropping from the orange button. The list of favorites is Specific for each browser. It can be exported to a XLS file.
