Note Types let you add custom fields to certain notes and categorize information you need to record that is not task-related.
For example, you could keep an open note for medical information about your client, add a note for phone logs, or use notes on your dashboard to track your personal productivity.
The Note types let you choose a note that will pre-populate a number of custom fields in addition to the free text area.
Then, when working with notes in a matter or dashboard, you can quickly pull up those fields relevant to the note.
Like all other elements, notes can have due dates, assigned users, labels and comments.
