Ansi UI ✔
This is a mash-up of my two favorite interfaces ─ Neav UI by Neal and Roth UI by Zork. I spiced it up with some of my own preferences. Both Neav and Roth can be downloaded here at Wowinterface and I recommend that you try both of those, before you try this one.
Open your World of Warcraft folder.
Remove your current "Interface". (Drag it to your desktop for example, so you don't delete it.)
Download Ansi UI and save the ZIP-file to your desktop.
Unpack Ansi UI and copy the "Interface" and "Fonts" folder into your World of Warcraft folder.
Launch World of Warcraft.
Shift+Alt-click to move the stance bar.
Type /gpaper to show a grid for aligning stuff like unit frames. Re-type it to remove the grid.
6.1 Changed almost everything.
5.0 Removed a few AddOns and added som new ones.
