Please excuse the simple question.
I have a project with all the actions now ticked and completed, yet the project is still there. I have even right clicked and marked it as complete - now I have a completed project with a rather fetching green tick. My question is how do I get rid of/archive this completed project from my view without right click deleting?
I have also tried changing the view to 'remaining' - no joy
