When I was looking around the database, I noticed that the tag database obeyed a tree form, which meant that tags could be stored with categories and subcategories and so on.

This is not a feature that's implemented, and it's high on my list of "features I'd love to have in DW" (possibly no 1 :-) ), and I have also written some tree algorithms using HTML/PHP before, so I thought I might try to give it a go and see if it went easily. However, when I went looking, there are no bugs in bugzilla about tree tagging, nor does there appear to be any information about this as a planned feature, despite the DB support.

So, I was wondering, can any of you please tell me more?
