This addon makes the character info window larger. That's it. A larger window means a larger paper doll (3D character model), so you can appreciate your gear and transmogs that much more.
The size of the window can be customized in the options (Esc Menu > Interface > AddOns Tab > Big Character Info). Background choices coming soon!
This addon goes great with DejaCharacterStats, since the larger window gives more room for stats! This addon has been designed for compatibility, and should work with any addon that adds information to the character info window.
