This is one of the 3 Audentio styles I have right now, and hopefully many more to come. Audentio is honestly one of the best design companies I've seen and not just for XenForo. These guys have amazing customer support. Take a look at the discussion thread, honestly, quick replies via PM and the style thread. The style is perfect, fast, flexible, configurable and especially innovative. I love it. It's no surprise that it's more used than the default XenForo style! About a month or two ago UI.X is all I could see used on boards. Why am I not surprised? Excellent style guys.
