TaskPaper 
For Mac users who want a simpler way to create lists. TaskPaper is a simple to-do list application that helps you stay organized. Unlike competing applications, TaskPaper is based on plain text files which offer you paper-like simplicity and ease of use.
TaskPaper makes it easy to create a list of your projects and their tasks so that you always know what needs to be done. It's simple to reorganize the list, create new items, mark items as done, and delete items that your finished with. You can also assign contexts (such as "home", "office", or "car") to your tasks so that you can later generate lists of all tasks assigned to a specific context.
