I am pretty sure the old version did this, because I always used to check "label" folders that had subfolders with individual 12 inch releases, once you hit the last song and clicked next vox would just play the first file in the next folder.
please bring that back! it was made vox so useful for me. also please fix that the next button behaves differently when your finder view is reversed or sorted by "last added", so vox just playes the next file that's in the finder underneath the currently playing file.
