Longtime hackpad and heavy paper user. One of my favorite aspects of paper is the ability create long flowing documents that progress as the project grows. Simply adding new updates to the top is a great way to keep all collaborators in the same documents without needing to create new docs and then have to manage multiple docs.
As the paper document grows it would be great to have the ability to collapse sections of the document into the headings.
It would provide a great way to keep large documents organized into sections.
It would also help to declutter documents to show sections that have been completed.
Im sure there are also alot of other edge cases for this.
