Bukkit

What is the enhancement in mind? How should it look and feel?

It would be great if I could use tab completion when using commands like edit - complete the name of the tag I am typing out, or for new complete the data type, or else give hints.

Please provide any additional information below.

Bukkit has a tab-completion event: http://jd.bukkit.org/beta/apidocs/org/bukkit/event/player/PlayerChatTabCompleteEvent.html
:)

Since there is so much typing and capitalization counts, it would really help speeding up command use.
