I use this setting to narrow important items due within a week, by means of flag control. You could manipulate your available tasks to the current day by using this method.
I use a slightly different method to control my today list but use this setting for my 7 days list because of the way I work. That way I clear my long term appointments list to give me a serious amount of time to prepare myself for extremely important appointments and tasks.
eg; a speaking engagement may be next year. I want to know it’s there and have plenty of preparation time as it approaches, not to mention avoiding date conflicts. When it appears within a month of the due date, I can work on it. When within a week I flag it, and it removes it from my long term list to 7 days list and will automatically appear in my Today list when the day arrives.
