When you stop tracking time using the timer, you might notice that the notes field is pre-populated with a list of activities. These smart notes are automatically added based on any actions you have performed in the related work item since you began tracking time.

Actions that will be tracked and added as smart notes include:
Created tasks

Commented on tasks

You can edit these, or add your own notes for more detail before you confirm your time entry.
