This is a compilation of addons that I've put together and optimized the buff and debuff settings for rogues!
I use this in 1920x1080 at my desktop and also in 1360x786 on my Notebook.
I'm pretty sure it will work on every widescreen monitor.
1. Back up or delete your old interface, and WTF folders.
2. Extract the interface, and WTF folders to your World of Warcraft folder.
3. Go to your WTF folder - rename the Account Name, Realm Name, & Character Name folders to suit your own.
4. Login to WoW.
5. Select the profile for "Vý" at each addon from the list below.
Maybe you have to play with the settigs till it fit to your system.
