Currently if Asuner makes files in different formats (say wav+ogg+flac) all those go into the same directory. I get a lot of requests to allow to specify the directory in the preferences.
Don't know if that would require some significant change in the preferences UI but it will certainly take a bit of effort changing all the code, since everything currently assumes all the files are in the same directory.
