UI.X for XenForo 1 was the original flagship template from ThemeHouse / Audentio. Although the look and feel has been redesigned in UI.X 2, we decided to use the same colors, fonts, and overall look as in XenForo 1 for the dark version. UI.X Classic Dark has been updated with UI.X 2 Framework which comes with a lot of new features.
