There are two ways of viewing completed tasks:
- By entering a project and clicking on "Get completed tasks" at the bottom
- By clicking on the Karma count in the top-right corner and then "View all completed".
The first option only shows tasks from this particular project and only those who are no longer on the active task list and doesn't show when they were completed. The second option shows tasks from all projects grouped by the date they were completed and includes the exact time of completion as well as each completion event of recurring tasks.
