Bob has simply put out one of, if not the, best add-ons going for XenForo. It is a gamebreaker that can easily run an entire site. I have never felt like I have bothered him asking a question, he's always replying to my inane questions like a champ. He goes completely above and beyond all support I have ever seen. This has so many uses it is not funny... reviews, garage, site showoff, recipes, trails, etc. You name it, 99% chance you can pull it off with this modification.
I suggest you to not sleep on this. It is well worth the price tag, and I question each release why he doesn't raise the price point. Amazing all around! Great work Bob.
