If you would like to remove a project from your Dashboard view, you can Archive it. Archiving a project is like deleting it except it remains visible in the Archived section of your Dashboard. Once you archive a project, all actions associated with it become inactive.

To archive a project, find a project that has been closed on your Dashboard. Hover over the ellipses and select "Archive" from the drop down menu. Finally, confirm your selection and the project will be archived.
