Managing The Appearance and Order of To Do Items     Changing the Appearance of “Due Soon,” “Due Today,” and “Overdue” Items NoteBook’s preferences panel contains options for how items that are “due soon” or “overdue” should appear.  For example, you can set NoteBook to draw “overdue” items in red.     “Striking Through” and Hiding Completed Items NoteBook’s preferences panel contains options for how completed items should appear.  For example, you can set NoteBook to draw complete items with a “strikethrough” or using a special color.   Choose Outline → Action Item → Hide Completed Items to set NoteBook to hide completed items.  NoteBook does not hide them immediately - it waits until you turn away from their page, or the start of a new day.     Keeping To Do Items Sorted with Auto-sorting You can set NoteBook to keep your to dos sorted as you make changes or add more.  With a parent cell selected, choose a sort from the Outline → Auto-sort menu.  The Prioritize sort was designed to manage action items, bubbling high-priority items to the top of the list, and bubbling completed items to the bottom.   If your action items live at the top level of a page’s outline, deselecting all cells and choosing a sort from the Auto-sort menu will set the page to auto-sort its cells.
