When browsing, have the ability to sort by the following options:
Mixed (what is currently the default).
I have my collection organised in a directory structure, and I do not use tagging.
When music applications scan the collection, the resulting database is often quite a mess.
I have always preferred using the file system.
When selecting music, I will sort by directories first, then files.
I have made some changes to the mopidy-file extension to handle this sorting, configurable in the mopidy.conf file, and it appears to work well.
I can make the changes available if there is interest.
