1. This is a handwritten notebook app, which is convenient for class, watching videos, reading books or recording what ever you want at any time.
2. In order to facilitate continuous writing, we use "area" instead of "character" as the input unit.
3. By separating the writing area and the display area, users do not have to switch between writing and zooming.
4. We do not provide the function of automatic completion, just take your time.
