I am trying to disable sweet berries from being usable in reacharound placing for the berry pips added in Berry Good. Putting "minecraft:sweet_berries" and "minecraft:sweet_berry_bush" in the config seem to have no effect, even after relaunching the game after both instances.

Also, I think some documentation in this config would help players a great deal, as whether you are supposed to list block items or blocks is ambiguous

This validates the item, so you should use the berry good item id
