My application accepts photographs from end-users. They will most likely select pictures that are recently taken. The initial view of Chooser, which shows the file structure of the user's Dropbox folder is therefore far less useful compared to the Photos view. Is there a parameter than can be passed to make the window opens to that view? Just a matter of saving an inevitable click.
I tried to examine the source code but the library appears to be written in Coffee.
There's no way to open a specific folder in the Dropbox Chooser. You can make the UI a bit nicer by using the extensions option to specify only image file types.
