The number in parentheses beside a view indicates the total number of notes in that view. A NEW icon beside a view indicates that new notes have been added to that view that you haven't read. Click the view that contains the notes you wish to read. You will see a new window, with a list of note titles in the selected view as explained below. Within your selected view, you will see a list of notes.
Turquoise squares indicate unread notes.
Red squares indicate that the notes have been read. Blue squares indicate that a note has been modified. Indented notes are Build-On notes. A Build-On is a separate note, but is connected to the note it is building from. Since note titles are links, they may appear as visited or unvisited.
