got this installed on my 2.3.0 board. Needed the Mr.P version of the hack as my forum template has gaps between the catagories.
Edited the colforumtableheader to allow the addition of the header to the boxes and put my own colforumbit code in place to suit my template style.
Thanks for the hack and the additions contained within the thread. (anyone want to see what i have done can visit
