I like how easy it is to edit notes and add links to other resources. The ability to see previous versions of notes helps me keep track of what I was thinking at the time that I wrote them. Sometimes it is hard to find where you were when you last edited a note. This makes it hard to tell if someone added something after you or if you just missed it. It would be nice if you could assign multiple people to different sections of a document. This allows me to have my colleagues help me write documents without having to ask them to edit every part of the document.
