It would be great to let Dropbox collaborate with Figma for a plugin that syncs dropbox image files in Figma. My company uses Dropbox to store all of our logos, but our design system is on Figma. This means that we will have to maintain two platforms whenever there's a logo update and it gets out of hand.
However, if we have this "Dropbox file plugin," we just need to maintain the dropbox folder. And if we update one of our files in dropbox, then that according file that was used anywhere in figma will also be updated. Similar to the main component and instances relationship that Figma has, but this time the Dropbox files are the "main component" whereas those files used in Figma are its instances.
