Karma is an webapp Uuser Interface(UI), that is build for different screen sizes(desktop, tablet and phone). Karma is build with a minimal and whitelabel feeling, with the idea that not every panel is the same, so karma can be setup in a minimal layout or go fully featured. The bigest feature of this theme are the modulized sidebars, as they can contain a lot of powerfull things.
