Mitty Todo List is a simple reminder program. And it never forget about undone tasks. It has two tasklists: ToDo and Done. ToDo tasks are the tasks which you had to do and are not done yet. The "Done" tasks are the tasks which you finished and will reoccure in the future. Mitty Todo List is different from other tasklist calendar programs because it never forget about undone tasks even if the occurence date passed and even if you seen the task in the list, only until you mark the task as done or delete it.
