Also, Andrey happily welcomes you to contact him if you encounter any issue. But unlike most developers I know thus far who just tells you it can't be done with their plugin/module, Andrey doesn't just stop at what his plugin/module can do. He attempts to understand my needs and how I wanted the plugin/module to function, then before you know it, he happily customizes his plugin to support my peculiar needs and implemented it for me in the backend, constantly following my emails and adjusting his code until everything is perfect.
I've never been so happy with a plugin purchase until now. This is truly the best I ever bought. 5 stars! Oh, I kept saying plugin/module because it comes together =)
One thing to mention, the set-up of the module does not totally fit in with what you might expect in relation to making template overrides. It is customizable via overrides, but not all of it, so I did have to modify the module itself for a couple of tweaks. That said, that's a minor gripe, and on the whole it it excellent.
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.
