Good recommendation. I am going to look into this mod and see if it would fit well with our community. If so I will put it on the approved mods list.
There is a difference between mods and plugins. The link you provided is a client side modification, this means that you would need to install it on your computer in order for it to work.
Plugins are server side modifications that apply to everyone on the server. If you really did mean to ask for a server side plugin change could you provide a link to one that you would like to see us implement?
