Leverage the UI from Onenote
One note has undergone much of the user learning to create a better IOS experience that is on Windows.
Why wont you use the learning from visual writing, image handling etc from Onenote to create the same great experience in whiteboard ?

Don't agree with this.. One note is a note taking tool and more personal. Whiteboard is a big white canvass for collaborating and idea generation.. Not the same tools in my opinion. Keep whiteboard app clean
