Emacs & Org font-locks

A simple trick to make the Org buffer looking more clear:

'(org-done ((t (:foreground "PaleGreen" :weight normal :strike-through t))))
'(org-headline-done ((((class color) (min-colors 16) (background dark)) (:foreground "LightSalmon" :strike-through t))))

will make your done items in the Org buffer strike-thru so that at first it is much more clear to decide on what to focus.
