Quick question about Node Categories

Is there a way to have the Category collapse to hide the other inside sections? I liked this feature on many other boards so I could close the ones that I wasnt interested in. Not sure if this is possible in Xenf. If you have a big forum the display list can be quite long with lots of scrolling.

Thanks Brogan, I noticed in the last post of the -blocks.5638 thread that it is now broken with the latest upgrade. I like the idea but I think I will wait to see if it goes "Core". It really should be core...(small plug for it)
