it is suprise that the version of android goodnotes is going to available for android users, but there are some feedback and problem on the design and template. First, for creating a new notebook, the image of the book cover is unclear and little bit vague, it is better to provide more clear version. Second, while in the book, for the pages, it is better to provide more size of the pen at a more accessible place, thus more time can be saved while changing the types of the pen. Third, it seems that the bar on the top is a little bit large, it is better for having smaller size to create a more large image of the notes
