I've noticed the way search results are reported is different - now, it lists all cases where the target string was found, even if that means re-listing the same thread multiple times.
Personally I prefer the old way, which only listed a thread once, as it can really save space in the results list.
Also - any chance the "location in" info could be back over to the right where it used to be? IMO that makes it alot easier to sift through results.
