If you need to mark any of your Documents temporarily or have them stand out from the rest of your documents, you can use “gold stars.” These gold stars are small yellow star icons that you can use to mark your Documents as “important.” Every document that you create will have a small star icon to the left of the document name.
Using Gold Stars
All Documents have the option of being marked as “Important” by using a gold star icon. You can mark Files with a gold star either when the Document is in editing mode, or when the Document is being viewed in your Folder.
You can also view all of the Documents that have been marked with a gold star when you click on the "tags" drop-down menu and then click on the "Important" option. See the image below:
