I've been using CN for a while for GTD as described in this post: viewtopic.php?p=885#p885
The current half support for hierarchy in the free version is very annoying. I get "p" and "r" tags that act like hierarchical parents but aren't displayed as such. If I delete a "nested" tag (which isn't a concept I should really have on the free version since hierarchical tags is [commercial]) eg p/NDL, all the p/NDL tags are renamed to p instead of being removed.
Tagging is for non-hierarchical organization. I'm happy hierarchical tagging was implemented because it was such a demanded feature but I was even more pleased that it was a commerical feature because I thought it meant I wouldn't get it on my free version. Instead I have the same hierarchical backend with broken UX

anything I can do?
thanks
