Subtext 2 introduces more advanced tools for analysis. As the package is now focused on deployment of such tools, previous functions will now be under miscellaneous section.
As of now, my development plan is in shambles and the only "advanced" algorithm you can currently access is SentimentAnalyser. But the analyser is quite good so I hope you can forgive me for that.
