Idea: Buddy list search/post symbol?

i was wondering if there was a way to search for all recent posts by members of your buddy list, or when you click the new post search, an icon appears on the envelope to show that someone you know has posted in a thread(idea similar to the symbol that shows that you have posted in a thread). It’s not exactly a team search, but I think it would be faster than calling up the buddies profile and searching for recent posts. This way, when you log in you see if anyone you know has posted. just an idea.
