Как в орг-моде настроить "Done" при выполнении всех задач в блоке?
> If you would like a TODO entry to automatically change to DONE when
all children are done, you can use the following setup:
(defun org-summary-todo (n-done n-not-done)
"Switch entry to DONE when all subentries are done, to TODO otherwise."
(let (org-log-done org-log-states) ; turn off logging
(org-todo (if (= n-not-done 0) "DONE" "TODO"))))
(add-hook 'org-after-todo-statistics-hook 'org-summary-todo)
Another possibility is the use of checkboxes to identify (a hierarchy
of) a large number of subtasks (see *note Checkboxes::).
