/Local is planned for the future. Just not a priority right now since we have party chat.
/Farm, like Syl said, is in development.
/Ignore does indeed not work. It's clashing between two chat plugins. It's on the list of things needing a fix.
We are unable to split up trust permissions anymore than they are already set. These are the main three:
/Trust Gives another player permission to edit in your claim.
/AccessTrust Gives a player permission to use your buttons, levers, and beds.
/ContainerTrust Gives a player permission to use your buttons, levers, beds, crafting gear, containers, and animals.
In your situation I would make your villager/animal region a sub claim, set permission to '/containertrust public' and simply not place any containers there.
