Bukkit

What is the enhancement in mind? How should it look and feel?
Would there be a way for you to disable the original command when performing an alias command.

Please provide any additional information below.
Basically my username is DanielBlakey but my essentials nickname is Danny. I've set up an alias for /m Danny, /msg Danny, /whisper Danny, etc. so it does send me the message but it still executes /m Danny which either means people with Danny in their name get the message too or they get an error saying player not found.
So not a major problem in my case but may be for other situations. Otherwise a brilliant plugin :)
