From most areas of My Juris, you can right-click an item and choose the option to Add to Favorites from the menu. That places the item on the favorites list.
The Favorites list can be cleared at any time by right-clicking and selecting Clear List. This will remove all items from the Favorites list.
Why use Favorites?
Most of the time, you will work with a limited set of Clients, Matters, etc. Adding these items to your favorites list makes the item easily accessible.
