i may be dumb, i thought this was added, but the wiki doesnt show "villager trades" as a req possibility.
and it fails to work when i try to set a req as "villager trades"

What kind of requirement would you like to see added? A player has to trade at least x times with a villager?

yes.

Will add that to do list!

hows #642 coming along?
bc that would open up a lot of custom reqs
