Dear Hoover Todd,
Thank you for your interest in our products!
If you don't want to see completed tasks on your task list, please do the following:
1. In "Filters Bar" choose "uncompleted" in "Completion" field.
2. Click on "Save filter as.." button.
3. Enter filter preset name. (for example: uncompleted tasks)
4. Click Ok.
Do the same with completed tasks, so you can shift between filters by one click.
