I like building big buildings in Minecraft, but it's hard to get certain materials—like clay—on some of my maps.
So I'm looking for an inventory editor that works on Mac OS X. I currently use Inside Job, but when I make a new save, it doesn't save a world in the right slot even if the slot is empty.
I can use an online Minecraft inventory editor, but that's generally a slow process and online inventory editors usually don't have everything.
