This is version 1.9 of my interface, a lot has changed since I first posted it here. First of all I finally got it to use less than 1MB memory and it basically needs no in-game setup, almost everything is done by lua.
1)Backup your WTF/Interface/Fonts(if you have) somewhere safe incase you dont like my ui
2)Extract WTF/Interface/Fonts folder in the .rar file into your wow directory.
3)Rename ACCOUNTNAME // SERVERNAME // CHARACTERNAME folders inside of the WTF folder.
4)Once ingame please do the following commands and select "Kepi UI" for the profiles
Go to your interface menu select "Addons" tab and go down to "StatBlockCore" and select KepiUI
Once you have selected "Kepi UI" for all those above please /rl to reload your ui and for all the settings kick in.
