With the development Version 0.5 Rangitaki has a complete new look, which is based on Material Design.
Why Material Design?
Material Design is influenced by paper and this element was for a long time the main material for the written word. Books, newspaper, letters and also diaries and logbooks were written on paper. So in my opinion is quite natural to use a design which is heavy influenced by this resource.
