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.
Installation ✔
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.
