The Archive Project feature helps users manage their own project list view. Each project can be archived on a user-by-user basis.
Inside each project page there is an ellipsis icon(...) at the top right corner.
While the complete menu options may change depending on your individual permissions, you will see an option to archive or unarchive the current project.
An archived project will be removed from your primary project list view and relocated to a list of archived projects. You can reference the list of archived projects by selecting Archived Projects on the left navigation bar.
