I'm not sure if it's just me but I'm having a real hard time trying to understand the very basics of the .NET API. The tutorial recommended that I create an app which I could then connect to via api secrets and what not. How do I access this app? Is there no way to create/edit folders and items in UI? Is it possible to use the API to connect to another person's dropbox folder (even though they don't have the 'app' that was created for api)?
