Daily I mark some tasks as completed. Some of the completed tasks are special (e.g. give a talk) and I would like to add them to my C.V.. It would be great if I could get a list of such completed tasks with the date in which they were completed. To make this possible I should be able to mark a task as C.V. material when I mark it as completed. When I decide to update my C.V. I use the list and empty it.
