Collection by Folder

[Gt1ult]

It will be great to add the option to see just albums/generes/artists for the selected folder. For example let's assume there are 2 main folders: one with all music well cataloged and tagged (Music) and another one with the music to be cataloged and tagged (TO_DO). It will be very useful to have the option to enable and make visible just the music inside one main folder (or all folders), depending on the will and needs.
