For those of you who use the HitsMode addon, Kodewulf has created an info panel plugin that integrates HitsMode into nUI... this is the first third party addon to nUI that I'm aware of.
You can find it by going to the "Optional Files" tab on the nUI download page at
http://www.wowinterface.com/download...=9108#optional, or you can go directly to
http://www.wowinterface.com/downloads/info11402.html to download it.
Many thanks to Kodewulf for doing this!
