Out of curiosity, can anyone from Dropbox explain why API v2 removed file type permissions? In v1, an app can request to only access image files (more info here). This gives the user confidence that the app won't do anything inappropriate using their Dropbox account. If an app only wants to access image files (like how Carousel does), the user will know that it won't be able to access sensitive text documents.
I'm curious why this type of permission was removed and v2 only supports "full access" or "app folder." Neither really seem to fit the purpose of many apps out there (like organizing just photos). I believe this change makes it the authorization process significantly worse as users are turned off by any app that wants full access to their account.
