Cải tiến UI-UX

Ở bản 2.3.4 mới nhất, banner giới thiệu tính năng mới chiếm diện tích màn hình, và đôi khi gây sao nhãng mà lại không ẩn đi được. Shop nên để vào mục thông báo trong ứng dụng, hoặc đưa xuống cuối màn hình. Thêm nữa mong shop sớm bổ sung tính năng đổi bố cục màn hình chính như trên app hanzi
