What do you want to see in Bukkit? API wise or performance wise. I think it would be nice for the developers to know what everyone else wants. Because they might miss out huge features that could widen Bukkit up hundreds more useful plugins. So, what would you like to see? I'm not saying that if you post it here it'll get implemented, it's just to share opinion. Personally, I would like to see the ability to detect dropped items, it would make for a lot more cool plug-ins.
