Box Notes - Ability to collapse/expand sections
Sometimes collaborative Box Notes can get VERY long. It would be great to have a little carat next to each level of heading that would allow you to compress/fold down the sections you're not working on.
Google docs also doesn't have this option. Lack of this option causes switching to different solutions (see example here where switching to dynalist is recommended: https://www.quora.com/Can-you-expand-collapse-paragraphs-on-Google-Docs-as-with-Word)
