Looking at the CK, there's soooooo much they could've done with number of
things to make this game of the decade pretty much.
Like I mentioned to Arclight on Steam already, the weapon/armor crafting in the
stock game is just a tip of the iceberg. If you add a new weapon/armor with
the CK, you can add a whole new recipe for it and that recipe can be ANYTHING
you want. Like 1 iron ignot or something, but this also allows for the crafting of
special custom weapons/armor. Like, say you have a shortsword and you want
it to have 5 uses that poison the enemy, you could just make a new weapon
and make a crafting recipe of
shortsword + [whatever you want].
Example, I want to make armor that has chameleon 100 (Credit to Arclight
for the idea

), I could give it a new ID in the CK and give it a recipe
like
leather armor + plant [x]
+ plant [y]
