For multidisciplinary knowledge management

I think it's a good feature to have, but I do wonder how many of the categories would end up with just 1 leaf node. It would also be quite a lot of work, given the average Roadkill user's usage.

I'm not saying no, I just don't want to add feature bloat - it feels like a plugin, with the plugins extended a little so they can change the add/edit page
