It can borrow a few things from OneNote e.g.
- cards resize automatically with text.
- OneNote starts with a cursor, clicking anywhere on canvas and writing is a single click operation.
- There are no hard borders around cards in OneNote.
- OneNote is WYSIWYG which this canvas isn't currently.
This is not a definitive list and I know its too early to ask for new features and stuff. Good things to consider IMO.
