1.9 is currently having work done in that area. Mose was originally working and added the expanding and collapsed sections but had to divert his resources elsewhere. I had a quick look at the code the other night and then mose said he would get back onto it.
I'm sure that by the time 1.9 RC1 is out around the end of the month we should have suitable category area.
Id just like to add for those others reading, that using HEAD or CVS code isnt recommended for production sites. If it breaks its more than likely upto you to fix it. whereas with a release you can submit bugs. We dont have bug tracking for development code.
