Oh, that wasn't me. IIRC it was the TMW Maker from TMW-BR Team (no longer compatible... *sigh*)
Ideally, Hocus would like something structured like this:
Which looks cool but have two core issues...
1. Spreadsheets are horrible to work with and to do that, they're not even a workflow tool!
2. It does not have meta content, so it cannot be reused to generate quests.xml nor wiki
So yea, pretty much without ideas... Ideally they should (more like, must) be generated directly from NPC files, but even parsing that with our inconsistent and ever-changing syntax sounds like a nightmare.
EDIT: Livio, please be sure to bring me flowers. Bees are optional. I'm sure they'll try to carbonize me when we start discussing about releasing at the end of the year ^_-
