@mine spawner chest is excellent way to find dungeons (especially with SilkSpawners), but it's a bit unfortunate how if there is, say, an enchanted_golden_apple in the chest there is no way to tell the client to pick it up.
When mining diamonds with @mine diamond_ore, baritone will wait to pick up the diamonds before moving on, but no such setting exists for non-Block items.

Something similar would be nice for chest_minecarts, but that probably deserves its own issue (currently they can be followed, but baritone doesn't know how to attack/break them).

change the mine loiter setting
