On the main page of your Outline Tool, you can use the main options menu to control how the sources, notes and ideas linked to your outline are displayed.

By selecting "Other Options" a popup will be shown allowing you to affect the display orders of sources, notes, and ideas.

For your sources, you can order them by author, publication date, creation date, or most recently added; or use MLA, APA, or Chicago Author/Date citation style.
For your notes, you can order them by title, oldest first, or newest first.
For your ideas, you can order them by title, oldest first, or newest first.
These display preferences are how you view your outline on this Outline Tool main page and also how a print-friendly version of your outline will be formatted.
