I believe the process of replying to posts in threads in XenForo can be improved a little.
The problem I have with the current way it works is that there is no clear visual feedback/confirmation that the enduser has actually posted their reply. Let me show what I mean by these screenshots:
Screenshot 3 is showing you what I see in WinXP/Chrome on my resolution. Maybe the only thing that is going on is that is has something to do with my resolution/setup, but I find it rather confusing that I can not immediately see what I have posted. I miss some kind of visual feedback that my posting is actually there. Obviously displaying my submitted posting would be enough of a confirmation, but on my setup XenForo does not show me my submitted posting. I have to browse down to it, to be able to see it.
