Hide Completed and Dropped Projects (Not Just Actions)

I’m pretty new to OmniFocus 2. I’ve searched through the menus and preferences without any luck.

Is there a way to hide projects that are completed or dropped? I seem to be hiding the actions, but not the projects even when the project’s status is one of those. Some of these projects have zero remaining tasks.

Thank you.

If you create a new project and inspect it, there is a “Complete when completing last action” check box. I used that last night for a sequential project and the project disappeared after completing the last action.
