I really want to find the function for check the works that I already done.
If there are no functions for that, I demand a refund, please.
You can view your completed tasks in 2 ways:
1. Enter the project in which they were completed and click on the circle to see tasks that were done in this one project.
2. Go to Karma -> View All Completed to see all completed tasks from all projects, filter them and see some productivity graphs :-)
