With To-Do categories you can order your tasks easily. You can name them the way you need and group your tasks in the To-Do list, using the categories.
If you right-click on the category you can set it as a standard. This way, this category is used for every new task you enter.
You can drag&drop a task into another category in your To-Do list.
If you click into the field "Subject" or hit F2, you can enter text directly into the To-Do list.
