I've been using this add-on now for more than a year, and I have only good things to say about it. My index page is more compact, so users don't have to scroll so much to find the forums they are looking for. It also simply looks better.
I want to thank you to the developer because of this great plugin. I was looking for a good modification to divide the node list in two columns and I couldn't find any modification compatible with latest XenForo version. I hope the developer will continue supporting this addon on future XF versions! :)
