I haven't been as active as I was in the early release of the game and the wiki but this is fantastic!
If it were up to me, I would direct tags to their Category page because as long as people fill out the templates for individual dishes/ingredients, that gets auto-populated anyway. Like -- chef-wars.wikia.com/wiki/Category:Festive
I think the only person who has access to that would be Fannsa, I tried getting into the file required to add the code but couldn't.
I'm definitely all for making things simpler and removing redundant actions! Let me see if I can set something up if my brain is functional enough for this. :P
