Summary of Spotter changes for search implementors and senders?

I know this was discussed but there were so many emails that I could not follow. So let me ask..was something finally done and integrated to search for an exact list of implementors and senders (not all methods matching a pattern)? I mean the exact behavior as you get when you do cmd+m and cmd+n. If so, how can I use it?

Thanks in advance,
