As a workspace admin, I'd like to know all project lists and be able to edit/change the setting of projects in one place.

If you create a project as private, you'd have to search all projects and modify permissions one by one whenever there is a new employee or there is a change in personnel.

It's considered inefficient because all the people who are set as project admins have to do this.

Therefore, it's necessary to set permission at the master account level(admin) which is in charge of general management.
