regarding your switch away from omnifocus… at the moment I am thinking about leaving OF too. But in the opposite way you do. You are going to a reduced plain text list, I was looking for a more visual approach of todo/task management. So I am going to droptask.com

But in omnifocus I am missing the “big picture” which droptask delivers
