Btex allows me to customise their skins as hell. Here is my very first self-made skin. This skin is something for your eyes, mainly addons may not be created for these.
The skin is mainly paladin themed, priests may like it too.
Copy the 4 Morwo-X.tga files in the World of Warcraft\Interface\AddOns\Btex\Skins folder. Ingame, type: /btex menu Go for <custom texture> Set name to Morwo, adjust size, positon and transparency to your screen-resolution and your preferences.
Enjoy it, cu
