Favorite thread option?

I was wondering if ATS does have something like it or had any interest in making a "Favorite" option for threads, since I think it would be great for managing threads for other threads for presentations, and organization. MyATS is the closest thing I could find to one, but it only shows current posts, rather then being...Chronological or Alphabetical like a library I guess.

Now it doesn't have to be out in the open how many times the thread gets favored, like a thread getting flagged or FB, but it would serve for better organization.
