On the project page you mention that there is a ToDo of "Enable File Deletion" -- I have a need for a personal project I'm working on to implement it (I'm using your module sort of as an API for Dropbox and I'm adding and removing files as needed). I have the right code to call $dropbox->delete but Dropbox API is giving me back "Unauthorized" (however, the DrupalD app has full read/write permissions to my entire Dropbox).

What is needed in order to implement deletion? I am good with code and very likely could submit a patch. Could you help point me in a direction?
