Quick intro: The Creation Kit Extender is a SKSE plugin that fixes the Creation Kit's bugs, enhances existing tools and adds new ones. Put simply, it's the http://www.gamesas.com/topic/1450528-rel-construction-set-extender/ for Skyrim.
I generally do not create work-in-progress threads for my projects but this one will be a long term undertaking and I'll be requiring community feedback on what to fix/add. I'd held off on working on this until Beth was done patching the game/editor, which it has now.
This thread will be the primary repository for requests, suggestions, etc.
