I recently asked @Mike John to upgrade a mod I had created for my 3.4 site, it basically does this (yet includes the who's online). It's good to see teraßyte back on IPS, releasing his mods. I actually think it's impressive to see such a wide range of mods being released for FREE, which I would be happy to pay for in fact (I almost did).
It would be nice if in the a future update may include hiding the IP from all areas, including the tools provided in 4.0/4.1 for those in usergroups that are team members below Admins. I personally believe this info should only serve top level admins, I do not see why being a team member with GM privileges would grant them permission to view the info. Yet this is a suggestion/request. I'm happy with the plugin and it works well.
Many thanks for releasing it.
