For me the smart add feature is one of the big features of RTM.

I use RTM a lot for delegating tasks. I know that I can also share lists. It makes it very easy to share tasks and you can use smart add to assign to a list. But if you work with a larger team, either you have a list for each member or you only know that a task is shared from someone in your group but not from whom exactly it came.

It would be awesome therefore to have a sharedWith option in smart add. That would save me from a proliferation of shared lists to share tasks fast.
