Coffee Admin Theme gives the dashboard a bolder look with sumptous dark tones and a textured background. The theme is fully compatible with the latest version of WordPress supporting the new fly-out menus. Because of this, the theme will not work as intended in older versions.
The plugin has options to switch between different themes, and I will be adding more themes over time.
You also get a great selection of Google Web Fonts to choose, further enhancing your dashboard experience.
