Creating smart lists in Remeber the milk

Recently I started using a fablous TO-DO manager called Remember The Milk (http://rememberthemilk.com) and was stuck at how to create a list which has tasks as per my

criteria.

There are various criteria attributes in RTM like by list, due date, complete/uncompleted status, tag, location, priority etc.

So, to create a smart list what you need to do is to first enter your requirement as a search criteria in the search box. For example say you want to create all the task in list "work" which were completed in last one week then you need to search: completedWithin:"one week of today" and list:"work"

As soon as you do that your will see an option to save it as a smart list. That's it. There is no option to create a smart list from the settings --> lists section.
