It's the one addition to Logic I cannot work without anymore. So much stuff to do with PlugSearch: Inserting plugins etc., finding sends, outputs etc, tracksearch, naming the IO with the AUX-names. All great stuff and very conveniently implemented.
All of this should be implemented into Logic per default, but as it is not, PlugSearch is the way to go.
Great work by Rinus at @speakerfood!
