I was just getting on line to ask about this. Desperately need something like this.

It is often easiest to search for for an task and add sub-tasks... I couldn't agree more with this request.

I would add that it's not only about adding sub-tasks. You can't even activate the quick menu on a search result, which seems really silly. I get search results, and I want to postpone them via Quick Menu, but I can't do that. I have to exit search, manually find the item (what's the point of search??) and then postpone it.
Search results should be treated just like the items that they are, and not some special object that you can't do anything with, other than view it.
