DayTasks

DayTasks lets you easily manage adding new tasks, removing tasks, marking tasks complete, archiving completed tasks to your done.txt file, and even filtering and searching through tasks in a simple way that lets you find certain projects or contexts easily. It also handles adding creation and completion dates to tasks for you. Try enabling Easy Line Breaks if you want the ability to add more details to your tasks – this is the feature I’ve always wanted to include in DayTasks.
