That is true. I have not added any features to try to automatically sync based on a folder, and even if you used the SD card or removable storage, adding new files to that wouldn't be picked up automatically. I also prepend files with an identifier so that multiple songs can use files that might be named the same thing without clashing. If you maintained the correct file names, but a different version was updated through syncing with DropBox, this would be picked up automatically.
