Bukkit

What is the enhancement in mind? How should it look and feel?
I would really love smarter zombies. With this I mean better pathfinding and bigger aggro range.
I've seen this in other plugins so I know it's possible. I hope you can add it.

I would also really love a better chest loot system. I already have a massive world with a lot of chest so I don't need new chest. Instead I want all the chests in my world to have your chest features. Is it possible to add a function to convert all chests in a world to loot chests?

Please provide any additional information below.
Another thing that needs some attention is the zombie spawning. They sometimes spawn in a block...

I forgot to mention some more nice features I would love to see added: - ender eye radio (global and local chat) - legg breaking and patching them up with bones
