In the library manager, the 'Library Summary' dialogue can be opened via the <Summary> button. In this dialogue, all libraries referenced in the project and those libraries that reference them are displayed in a tree structure. The column 'Number of Occurrences' shows the number of places where this library is referenced by other libraries.
If a library is selected in this dialogue and the button <Display all occurrences in the library hierarchy and close dialog> is pressed, the dialogue is closed, the tree structure is opened in the library manager and the library that was selected in the dialogue is marked in the tree structure. The same happens when the library is double-clicked in the 'Library Summary' dialogue.
