Favorite and Unfavorite Files and Folders

How to Favorite and Unfavorite Files and Folders:

On the Sidebar, the star designates an area that can contain any files or folders that you would like to add to your "Favorites." Favorites are a personal setting and will not be applied globally across the account.
To add a favorite, click the actions menu next to that item and select "Favorite."
This will add a star to that item and add it in a list of "Favorites" in the sidebar.
If you would like to choose multiple items, select the box next to each item, click the top actions menu and select "Add to Favorites."
To remove items from your favorites you can use the "Actions" menu next to the item, or click the "X" next to that item in your "Favorites" list on the Sidebar.
You can also rearrange the items displayed in favorites using the "Grabber" icon.
