When adding files to a playlist, often a directory corresponds to a CD, but we can't add the entire directory at once; we have to add each file individually within the directory. This is very inconvenient. Thank you for your hard work; this is excellent software.

It would be perfect if we could specify a directory to search string, with the search results listing directories first and files second. However, this feature might be quite difficult to implement.
