Fair point. OneNote online handles it quite well however. Whether it would be too bloated would remain to be seen. It could be something like a switch from "Classic" to "Freeform canvas". Also, if it has switch to a different format (not html), why not?
I love EN, but there is one single feature that OneNote has that makes me seriously consider switching. ITs the fact that you can write anywhere on the page. Not limited like it is in traditional word processing. You write one paragraph here, another there. Then you can drag them around as if cutting and pasting them on a piece of paper. This would be a tremendous upgrade for me.
