But i am saying again this is a very good module as it is!
In short, htere is few things:
1. very confusing modul interface
2. no documentation, detailed demos, examples of work
3. problem with hidden menu item. If you choose to force itemid for search results and itemID is hidden menu item, when url is active, somehow broke menu functionality (tested on RT templates).
For joomla! 2.5 works great.
