I believe you may be referring to my post on the subject (main post). Whilst there is a bit of fiddling to set up the dashboard in the first place, after that, any new tasks simply need any one of a series of tags to be added and they will appear on your dashboard that number of days in advance and remain there until completed.
The dashboard can also be set as your default home view.
Obviously this is not ideal or right for everyone, but it is quick to use once set up.
