Nesting/Grouping of thoughts
Ryan G commented
I just joined and this was one of my immediate desires. My main motivation for joining was to help compartmentalize all of the projects I'm juggling. If I could group them by priority it would be great. Because if I add every project I have up in the air right now. It would be too overwhelming to really get the compartmentalization I'm looking for.
A useful feature indeed. GitBook implements such a feature in its solution (see gitbook.io).
