Please save vertical space, like hide the top bar where it shows my account, the name of the note, etc. these are useless while I am writing.
The tool bar shoule be floating and have a vertical version like the original iPad Memo App.

I use this tool for online lesson as a teacher, and use iPad version and Windows Beta version both.
Considering most PC screen are 16*9 wide, so, please make the writing space more high by hiding the top bar and a floating tool bar.

This is not only for Windows Beta, iPad and Mac version should also be like this
