As smart lists are designed today, a selected category as criteria in a smart list doesn't include product in it's sub-categories. That limitation has at least two negative consequences:
The need of extra admin when you create a smart list, since you have to mark plenty of sub-categories instead of only one single click
The need of keeping that smart-list up-to-date when new sub-categories are created since they don't get automatically included in the search criteria

What's the status on this idea? Is this a feature we can look forward to having in Litium anytime soon?
