Update patch. It does work now for adding subfolders.
TODO for improved folder support:

• Automatically add folders all path components behind "Documents" in [MLMediaLibrary addFilePath:]
• Add support for folder hierarchies to MLLabel

This is cool stuff. Does it work with the latest version of MediaLibraryKit, which includes slightly different behavior regarding file path handling? Let me know, if I can be of any help there.

I don't see any recents change in MediaLibraryKit regarding file path handling.
This patch works with http://git.videolan.org/?p=MediaLibraryKit.git;a=commit;h=eb2587e0c2220ce6766762e4599f3ddbfe86996b.
I've sent a full patch to Caro for testing and pushing.
