Roon needs to provide a Folder/File DISPLAY of audio files listed by directory structure from the hard drive. Roon’s arrangement of content is very slow and cumbersome when dealing with thousands of artists and albums from those artists. Additionally, Roon does not always get it right when arranging content into various categories. The majority of end users arrange their content on a hard drive volume in a very specific way to facilitate quick access. Roon needs to provide a Folder/File view of the content and make it navigable for accessibility purposes.
