Wuu - Wow Ui Updater
Wuu is a program that can update most of your addons.
It has all the addon locations from cosmos and ace in it, So with one touch of a button you can update all those addons rather then spending 5 hours doing it manually.
It also can update many popular addons not affilated with the big names such as cosmos and Ace.
So Things like Omen, ktmthreat.
This im afraid does not Cover ALL addons but it will cover a majority of them.
