I am quoting from Charles Cave's "How I use emacs and org to implement GTD" He shows has two configuration lines: #+PROPERTY: Effort_ALL 0:10 0:20 0:30 1:00 2:00 4:00 6:00 8:00 #+PROPERTY: Effort_ALL 0 0:10 0:20 0:30 1:00 2:00 3:00 4:00 8:00 with one #+COLUMNS: line in between Can someone throw some light on this?
