IMPORTANT: First of all don't forget that you should create your own threads at Suggestions: Tweaks & Small Features or Suggestions: Bigger Features in order to demand for a new feature being added to XenForo.
Even when 1.2 introduced a lot of awesome new stuff, the goal of this topic is to share the features that we need in the core of XenForo before migrating. For example the only one that prevents me from migrating from vB 3.8 is basic album functionality (with likes, comments, and an importer obviously). I need basic album functionality in the core of XenForo.
So what are the features that you're waiting for in order to make the switch to XenForo?
