The current implementation of the chooser works well enough for personal, relatively infrequent use. However, navigating to a specific folder from root every single time you load the chooser gets irritating in a high-use / enterprise context with complex folder structures.
Please add support for a 'defaultPath' attribute in the 'options' object passed into Dropbox.choose(), which overrides the default view of recent files or the root Dropbox folder with a more relevant file path for a specific use case!
Either that or add some functionality to 'favourite' specific folders so they show up in the nav bar on the left of the chooser?
Seems like a fairly obvious feature that'd make using the chooser much better from a UX point of view!
