Three important functions
Thanks for your application that I always use everyday.
But it will be more convenience if three functions improve.
First, To swipe a page by hand gesture. It is really inconvenience to click the button every time.
Second, A pen that erase few minutes later automatically. I really suggest it must be a very helpful function when we study with this application.
And last, it is inconvenience to move when page is zoomed. Two fingers to zoom up the page, and move with only one finger is more convenience to other users.
Thanks for reading my suggestion. I really promise it become a greatest application in many other memo apps.
