I like a lot of pages that are being made with Dropbox or Dropbox Paper. It would be nice if some example pages or section could be made into templates.
When adding files in a folder, they keep changing order. We can sort files according to size, name, etc. We can rearrange the order of the columns. But we cannot rearrange the order of our files, like dragging it down or up. Or as @mlippmann mentions a tree structure, which would mean being able to grab a section and dragging it up or down in your index list (not only within 1 folder).
