So, I had some extra time and created this wiki page:
Team Fortress 2 Item Attribute Indexes
Since it's a wiki page, other people can edit it. Right now, it's just a list of all the attributes in order... should they be split up by positive/negative effects? Split by class (for the attributes that only affect one)?
Also, I'm in the middle of redoing the
Team Fortress 2 Item Definition Indexes wiki page using tables. There's far too much info there for simple lists any more.
