The items in the Favourite List can be viewed and edited in the same way as the elements of the Local Corpus (right click and View/Edit Selected). This means that if you make changes to your favourites you have to right click on them and select Save Changes to Disk to make them permanent (or use Ctrl/cmd+S). The favourites which have been edited turn in blue which indicates this element still has to be saved locally.
Once you have completed your Favourites list, you can start using it. Let's say you want to add a particular Actor to a session - in order to do this choose the node in question, right click it and choose Favourites, Add from Favourites and click on the right actor. You can also do this by "drag and drop".
