I really like the XenStaff add-on and I think it would be awesome if it could be officially put into XenForo. I find it really useful on multiple communities for when I want to quickly contact a staff member.
And then secondly I would love it if the nodes as tabs add-on could be put into XenForo. It's an amazing add-on and it would be cool without having to install the add-on.
What do you guys think? Separate the thread if you really want.
