Ratings and reviews

very very good for a cellphone .. one recommend would be to add exporting pdf as rtf and try to improve 'screen handling' or 'sensitivity' a bit to make screen access a bit more accurate

It's in Chinese lettering with no way of changing language

다른 이름으로 저장은 어떻게 할 수 있는지요? 편집후에 우측상단에 저장버튼 있다고 하는데 그건 다른이름 저장이 안되는 거 같네요. 사용이 직관적이지 않고 숨은 구림 찾기 하는 느낌이네요.
