This is just a wonderful framework. Very flexible, attractive, easy to customize. $30 is peanuts for the quality and flexibility of this style - I was all set to pay for a custom skin to be created for our upcoming transition to XF, but this is far better than anything I could have had created on the fly.
Finally, the author is extremely patient and helpful, answering questions and even providing additional functionality in the discussion thread. Can't recommend this highly enough.
